Plant Systems and Responses

The spots growing on these leaves are caused by disease. Which two function are likely not functioning properly, allowing the disease to grow.

• Cell Cycle

• Cellular Respiration

• Meiosis

• Immune response

Which vascular structure is responsible for carrying important nutrients from the leaf to the rest of the plant?

• Xylem

• Phloem

• Pollinators

• Pollen and Ovary

Which type of cellular transport is important in the absorption of water from the soil into the roots and xylem?

• Simple diffusion

• Active transport

• Pinocytosis

• Osmosis

The process of transpiration is when water leaves through the stoma. The guard cell allows the stoma to open during humid conditions. When the stoma is open, what gases can enter and escape the plant?

• oxygen will enter the cell and carbon dioxide will leave

• hydrogen gas will leave the cell and oxygen will enter

• carbon dioxide will enter the cell and oxygen will leave

Which structure in the leaf allows for gas exchange?

• the waxy cuticle

• the xylem

• the phloem

• the stoma

Which part of the plants vascular system has a direct impact on cellular respiration?

• Xylem

• Phloem

• Pollen

• Stomata

Opening and closing of the stomata of a leaf is directly important for the process of

• Photosynthesis

• Cellular respiration

• Cell cycle

• Mitosis

This chemical equation represents the process of

• Photosynthesis

• Cellular respiration

• Reproduction

• Meiosis

Which organ of the plant conducts the process of photosynthesis?

• Shoots

• Roots

• Leaf

• Trunk

TRUE OR FALSE: All animal cells have a mitochondria, but plant cells do not.

• True

• False
