Why does the animal cell absorb water while the plant cell does not?
Animal cells utilize osmosis to absorb water in order to maintain proper cell function and prevent dehydration. Plant cells have a rigid cell wall that exerts pressure to balance the inward force of water absorption, preventing excessive water uptake. This structural difference allows plant cells to regulate water intake effectively and maintain turgor pressure without absorbing excess water.
What do guard cells close to prevent excess water loss?
Guard cells close to prevent excess water loss by closing the stomata, which are small openings on the surface of leaves. When the stomata are closed, it reduces the amount of water vapor that can escape from the plant through transpiration. This helps the plant conserve water during dry or hot conditions.
Why is the leaf cell important?
Leaf cells play a crucial role in photosynthesis, converting sunlight into energy for the plant through the process of photosynthesis. They also help regulate gas exchange, allowing for the intake of carbon dioxide and release of oxygen. Additionally, leaf cells store nutrients and water for the plant's growth and survival.
What kind of cells are plant cells?
All plant cells are eukaryotic cells
Does the plant cell lack a nucleus?
Plant cells must have a nucleus to make cells.
How does the plant take in the ingredients for photosynthesis?
they intake it through there cells and the roots
Which of the structures prevent plant cells from noticeably changing shape?
The cell wall
What plant alkaloids are used to treat cancer?
Plant alkaloids prevent cells from dividing normally. Vinblastine and vincristine are plant alkaloids obtained from the periwinkle plant.
Why are cork cells plant cells?
Cork cells are plant cells because they are derived from the cork cambium in woody plants. These specialized cells have thick walls made of suberin that provide support, protect the plant, and prevent water loss. Additionally, cork cells are dead at maturity, unlike most living plant cells.

Chloroplasts are found in what types of cells?
Plant cells, not animal cells.

Are hypotonic solutions found in animal cells plant cells or both?
Hypotonic solutions can be found in both animal and plant cells. In a hypotonic solution, the concentration of solutes outside the cell is lower than inside the cell, causing water to move into the cell. This can lead to swelling and potentially bursting of the cell if not regulated properly by the cell.
Why do plant and bacterial cell not burst in a very dilute solution?
Plant and bacterial cells have cell walls that provide structural support and protect them from bursting in a very dilute solution. The cell wall helps maintain the shape of the cell and prevents excessive water uptake through osmosis. Additionally, bacteria often have mechanisms to actively regulate their internal osmotic conditions to prevent bursting.
Why can an animal cell change shape but a plant cell cannot?
Plant cells have rigid cell walls made of cellulose that provide structural support and prevent drastic changes in shape. Animal cells do not have a cell wall and rely on their cytoskeleton for support, allowing them to change shape more easily.
Does a lichen have plant cells or animal cells?
Plant cells.
