Animal cells do not have a cell wall. Instead of a cell wall, the plasma membrane (usually called cell membrane when discussing animal cells) is the outer boundary of animal cells. Animal tissues therefore require either external or internal support from some kind of skeleton. Frameworks of rigid cellulose fibrils thicken and strengthen the cell walls of higher plants. Plasmodesmata that connect the protoplasts of higher plant cells do not have a counterpart in the animal cell model. During telophase of mitosis, a cell plate is formed as the plant cell begins its division. In animal cells, the cell pinches in the center to form two cells; no cell plate is laid down. Centrioles are generally not found in higher plant cells, while they are found in animal cells. Animal cells do not have plastids, which are common in plant cells (chloroplasts). Both cell types have vacuoles, however, in animal cells vacuoles are very tiny or absent, while in plant cells vacuoles are generally quite large.
What else can I help you with?
How does the stomata closing help a plant?
Closing stomata helps prevent excessive water loss through transpiration. It also reduces the risk of pathogens entering the plant through the stomata, helping to maintain the plant's health and overall function.
What would happen if a plant lacks stomata?
Water could not pass through it and it could not function.
What is the function of the quard cell in a plant?
Guard cells are specialized cells located around the stomata, or pores, on plant leaves. Their main function is to regulate gas exchange by controlling the opening and closing of these stomata. When guard cells absorb water, they swell and bend, causing the stomata to open, allowing carbon dioxide in for photosynthesis and oxygen out. Conversely, when they lose water, the stomata close to prevent water loss, helping the plant maintain its water balance.
Why are stomata located on the underside of the leaf?
As the upper surface is covered with a waxy cuticle which protects the plant from dehydration if the stomata were covered by a cuticle they would not be able to function.
Which product of photosynthesis is released out of the plant through the stomata?
Oxygen is released out of the plant through stomata as a product of photosynthesis.
Function of stamates in a plant?
The stomata in a plant has many important functions. Located on the leaves of plants the stomata take in air for plant respiration and aid in photosynthesis.
How are stomata and fish gills the same?
They both make the plant and fish breath
Relate transpiration to the function of a stomata?
The stomata are pores on the bottom side of leaves that allow transpiration. When the plant does not recieve enogh moisture they close and the plant wilts.
How does the stomata closing help a plant?
Closing stomata helps prevent excessive water loss through transpiration. It also reduces the risk of pathogens entering the plant through the stomata, helping to maintain the plant's health and overall function.
What are the stomata and what is their function?
stomata are Small pores present on leaves of plants. it helps in photosynthesis by exchanging gases and it also helps in transpiration of plant.
Is lyososome a plant or animal cell?
Lysosomes are found in animal cells and are responsible for breaking down and recycling cellular waste. Plant cells have similar structures called lytic vacuoles, which serve a similar function to lysosomes.
What is the function of transpiration in plants?
The process of water moving out of the plant through tiny stomata holes.
What would happen if a plant lacks stomata?
Water could not pass through it and it could not function.
Which part of the human body is most similar to the stomata in plants?
It's the skin. Stomata are pores in the plant leaves through which water vapour escapes the plant. The human body loses water in the form of sweat through the sweat pores in the skin.
What is the function of the quard cell in a plant?
Guard cells are specialized cells located around the stomata, or pores, on plant leaves. Their main function is to regulate gas exchange by controlling the opening and closing of these stomata. When guard cells absorb water, they swell and bend, causing the stomata to open, allowing carbon dioxide in for photosynthesis and oxygen out. Conversely, when they lose water, the stomata close to prevent water loss, helping the plant maintain its water balance.
Why are stomata important for plant physiology and overall function?
Stomata are important for plant physiology and overall function because they regulate gas exchange, allowing plants to take in carbon dioxide for photosynthesis and release oxygen and water vapor. This process is crucial for plant growth, energy production, and maintaining proper water balance within the plant.
Why are stomata located on the underside of the leaf?
As the upper surface is covered with a waxy cuticle which protects the plant from dehydration if the stomata were covered by a cuticle they would not be able to function.
