Components of Flowering Vascular Plants

What is anther's role?

Produces pollen (plant sperm).

What does the pistil consist of?

Stigma, style, ovary, ovules.

Define style (role).

Connects stigma to ovary, transports pollen.

Define ovary (role).

Located at the base of the carpel, holds the ovules.

Define ovules.

Part of the pistil that produces eggs.

What is germination?

The process by which a plant grows from a seed.

Which part of the plant is the main site of photosynthesis?

The leaves.

What do plants rely on for energy?

Glucose.

What is the male part of the flower called?

Stamen.

What does the stamen consist of?

Anther and filament.

Define filament's role.

A long, thin structure that supports an anther.

What is the female part of a flower called?

Pistil or carpel.

Define stigma's role.

A sticky structure that catches pollen.

What is pollination?

Transfer of pollen from anther to stigma.

What is fertilization?

Joining of egg and sperm.

What comes after fertilization?

Fructification: formation of fruit.

What do fertilized eggs become?

Seeds.

Why are petals brightly colored?

To attract pollinators.

Parts of a flowering plant.

Root, stem, leaf, flower.

Transport structures of plants.

Xylem and Phloem.

The…transports water and minerals from roots to leaves in one direction.

Xylem.

The…transports glucose from leaves to other parts of the plant.

Phloem.

Which transport tube contains live cells?

The phloem.

Are the cells in the Xylem living?

No.

The…anchors and supports the plant.

Stem.

Stomata

Tiny pores, mostly found on the underside of leaves

What is the primary role of stomata?

To let gases in and out of the leaf.

What are the two primary gases plants absorb and release?

Carbon dioxide and oxygen.

What is the other function of stomata?

To let water escape through transpiration.

Define transpiration.

The loss of water vapor from the plant to the air.

Each…is controlled by two guard cells that open and close the hole.

Stomata.

When the plant has plenty of water, the guard cells…the stoma.

Swell and open.

When it's dry, the guard cells…the stoma to help the plant save water.

Close.

Role of roots.

Absorb water and minerals, anchor the plant.

Why are leaves thin?

To shorten diffuse distance of gases.

What do chloroplasts do?

Site of photosynthesis.

Role of stems.

To support the plant and transport substances.

The xylem carries…

Water and minerals.

The phloem carries…

Sugars and food.
