Plant cells have three organelles that animals do not: a central vacuole, a chloroplast, and a cell wall. The central vacuole is a large organelle, occupying up to 80% of the cell’s volume, which stores water and other solutes needed to keep the cell turgid and control its osmotic pressure.
A chloroplast is an organelle that contains chlorophyll and performs photosynthesis in plant cells; it is absent in animal cells. Lastly, plant cells also have cell walls made of cellulose to provide structural support and protect the cell from its environment; animal cells lack cell walls.

What 3 organelles are only found in plant cells?
The three organelles that are typically only found in plant cells are chloroplasts, a central vacuole, and the cell wall. Chloroplasts are what give plants their green color, and are the sites in which photosynthesis takes place.
The central vacuole is a large, membrane-bound organelle that stores water, enzymes, inorganic salts and other substances to help regulate water balance in the cell. Lastly, the cell wall provides support and protection for the cells.
The cell wall is made from a variety of materials, including cellulose fibers and lignin, which gives rigidity and strength to the cell wall.
What are 3 differences between plants and animals?
1. Cellular Organization: The cell of a plant is far more complex than the cell of an animal. Plants are autotrophic organisms, meaning they are able to make their own food, while animals require the consumption of external sources of nutrition.
The cell wall of a plant is composed of cellulose and gives plants rigidity and strength, while animals lack a cell wall.
2. Reproduction: Plant cells are capable of both asexual and sexual reproduction, while animal cells can generally only reproduce sexually. Plant reproduction does not usually require two separate parents and can occur through fragmentation, budding and other means.
Sexual reproduction in plants involves alternating haploid and diploid generations, meaning that the plant must switch between producing eggs and sperm. In animals, reproduction generally requires two separate parents of the opposite sex, and only the diploid form of the organism is reproduced.
3. Mobility: Plants are generally stationary objects since they rely on their environment for resources, while animals are able to actively acquire their own resources by seeking out food, mates, or territory.
Mobility also allows animals to evade predators and seek out potential new sources of food that may be beneficial to them. Plants, on the other hand, rely on their surroundings and cannot escape threats or find new resources on their own.
Which type of organelle is found in plants but not in animals quizlet?
Plants contain an organelle that animals do not, which is called the chloroplast. Chloroplasts are specialized organelles that act as the powerhouse of the plant cell, and they are what gives plants their green color due to the high concentration of chlorophyll they contain.
Chloroplasts are responsible for photosynthesis, the process by which plants convert light energy into sugar energy. While photosynthesis happens in animals as well, plants are unique in that they are the only organisms that are capable of performing the entire process within their cells.
Chloroplasts contain all the necessary components to facilitate the photosynthesis, such as pigments that absorb light, electron carriers, enzymes to catalyze the reaction, and the calvin cycle. Chloroplasts are also responsible for the production of oxygen, which is a by-product of photosynthesis and is essential for the survival of most organisms.
What are 3 common organelles and their functions?
The three most common organelles are the nucleus, mitochondria, and endoplasmic reticulum. The nucleus is the organelle that acts as the control center of the cell, containing and organizing DNA, and working to control cellular activities.
Mitochondria are responsible for energy production, taking in nutrients and oxygen and converting them into the energy that powers the cells. The endoplasmic reticulum is a network of interconnected proteins and membranes and acts to move materials around the cell, ensuring that proteins, lipids and other molecules are in their correct places.
It also helps to form a protective wall around the cell, which is important for transporting molecules in and out. Additionally, it plays a vital role in manufacturing, packaging and shipping proteins to their designated locations.
What are 3 organelles that both the plant and animal cells have in common?
Three organelles that both plant and animal cells have in common are the cell wall, the nucleus, and the endoplasmic reticulum (ER).
The cell wall is a semi-permeable membrane located on the outside of the cell. It provides protection, as well as structure and support for the cell. In the case of plant cells, the cell wall is composed of cellulose and is much thicker than the cell walls of animal cells.
The nucleus is the main control center for the cell. It is responsible for storing genetic information and regulating metabolic processes. The nucleus is surrounded by a nuclear envelope, which separates its internal structures from the cellular environment.
Both animal and plant cells contain a single, central nucleus.
The endoplasmic reticulum (ER) is responsible for synthesizing and transporting proteins and lipids. It is composed of a network of interconnected, hollow tubes. In eukaryotic cells, the ER membrane is continuous with the outer nuclear membrane.
This is why the ER is considered the connecting link between the nucleus and the cytoplasm. Both animal and plant cells contain an ER.
Which are present only in plant cells?
Plant cells are unique and contain many features that are not present in other types of cells. These features give plants the ability to photosynthesize and obtain energy from the sun. Some of the features that are present only in plant cells are a cell wall, chloroplasts, and a large vacuole.
The cell wall is a rigid structure that surrounds the entire cell. Its purpose is to provide structural support, protection, and regulate the transport of materials in and out of the cell. It is composed of cellulose and other compounds such as hemicellulose, pectin, and proteins.
Chloroplasts are the organelles responsible for photosynthesis, the process by which plants convert light energy into chemical energy. They consist of a surrounding membrane and many internal thylakoid membranes which contain the proteins needed for light reaction and the Calvin-Benson cycle.
The large vacuole is another distinctive feature of plant cells. It occupies a large amount of the cell’s volume and provides for the storage of substances and maintenance of the cell’s turgor pressure.
Additionally, it helps to maintain the shape of the plant cell and is filled with a solution that contains molecules like potassium and calcium ions, sugars, and amino acids.
All of these features are present in plant cells, but are not found in other types of cells.
What can plants do that animals Cannot?
Plants are able to produce their own food through photosynthesis, a process that uses energy from the sun, carbon dioxide, and water to create carbohydrates. This is something that animals cannot do on their own and must obtain food from other sources.
Additionally, plants are stationary and their roots are able to absorb the essential macronutrients and minerals found in the soil which animals cannot do. Plants also provide shelter and food for animals, which animals are not able to do for themselves.
Plants are also able to breathe in carbon dioxide and release oxygen, creating a natural cycle of air regulation, something which animals cannot do.
