RC 04 Plant Systems and Interactions

What is the main function of leaves in a plant?

• Attracts pollinators

• Produces pollen

• Food production and photosynthesis

• Reproduction of the plant

What is the role of petals in a plant?

• Converts light energy to chemical energy

• Produces ovum/ovule

• Attracts pollinators

• Holds the pollens

What is the pistil composed of?

• Anther and filament

• Stigma, style, and ovary

• Stamen

• Filament and ovary

What does the ovary of a flower develop into after maturation?

• A leaf

• A petal

• A seed

• A fruit

What are the main parts of a stamen?

• Stigma and style

• Anther and filament

• Ovary and ovule

• Petal and leaf

What is cross-pollination?

• The transfer of pollen from the anther to the stigma of the same flower

• The process where a plant pollinates itself without the involvement of another plant

• The transfer of pollen from the anther of one flower to the stigma of another flower on the same plant

• The transfer of pollen from the anther of one flower to the stigma of a different flower on a different plant of the same species

What is the role of pollinators in cross-pollination?

• They produce pollen

• They help disperse or spread the pollen or seeds

• They consume the pollen

• They fertilize the ovule

What is self-pollination?

• The transfer of pollen from one plant to another of a different species

• The transfer of pollen from the anther to the stigma of a different flower on the same plant

• The transfer of pollen from the anther to the stigma of the same flower or another flower on the same plant

• The process where insects transfer pollen from one flower to another

What is the function of stomata in plants?

• To absorb sunlight for photosynthesis

• To transport nutrients throughout the plant

• To facilitate the exchange of gases and transpiration

• To protect the plant from predators

What happens when the guard cells of stomata open?

• The plant loses its ability to exchange gases

• The stomata close, preventing water loss

• The stomata open, allowing for the exchange of gases and transpiration

• The plant wilts due to excessive water loss
