Plants

Angiosperm

A flowering plant that produces seeds enclosed in a protective structure, most plants are angiosperms. Angiosperm. An angiosperm is a plant that has flowers and produces seeds protected inside fruit.

Cambium

The plant cell layer that makes new phloem and xylem cells. Cambium. Cambium is a thin layer in plants that helps them grow by producing new cells for transporting nutrients and water.

Chlorophyll

The green pigment in plants that uses light energy for photosynthesis. Chlorophyll. Chlorophyll is a substance in plants that helps turn sunlight into food.

Dicot

A flowering plant whose seeds have two leaves. Dicot. Dicots are plants that start with two seed leaves, or cotyledons, which helps them grow.

Flower

The reproductive structure of an angiosperm. Flower. A flower is the part of a plant that helps it reproduce by producing seeds.

Frond

The leaf of a fern. Frond. A frond is the leafy part of a fern that helps the plant make food through photosynthesis.

Fruit

The ripened ovary of a flower, it contains seeds. Fruit is the part of a plant that develops from the flower and contains the seeds.

Germination

The growth of a new plant from a seed. Germination. Germination is the process where a seed begins to grow and develop into a new plant.

Gymnosperm

A plant that bears seeds in cones, instead of fruit. Gymnosperm. Gymnosperms are plants that produce seeds without a protective fruit, often in cones.

Monocot

A flowering plant with one seed leaf. Monocot. Monocots are a group of plants that have seeds with a single leaf, like grasses and lilies.

Nonvascular plant

A low-growing plant that lacks true vascular tissue, like moss. Nonvascular plant. Nonvascular plants are simple plants that absorb water and nutrients directly through their surfaces instead of through specialized structures.

Ovary flower

The lower part of a pistil that produces seeds in ovules ovary. An ovary is the part of a flower that contains ovules, which develop into seeds after fertilization.

Ovule

The ovary of a flower, it contains eggs. Ovule. An ovule is the part of a plant that develops into a seed after fertilization.

Petal

Colored leaf-like part of a flower. Petal. A petal is a part of a flower that is often colorful and helps attract pollinators like bees and butterflies.

Phloem

The vascular tissue that transports food in plants. Phloem is a part of a plant that moves nutrients like sugars from the leaves to other parts where they are needed.

Pistil

The female reproductive organ of a flower. Pistil. The pistil is the part of a flower that includes the ovary, style, and stigma, and is responsible for producing seeds after fertilization.

Pollen

Tiny grains that contain the male gametophytes of a flower. Pollen is the powdery substance produced by plants for reproduction, allowing them to fertilize other plants.

Pollination

The transfer of plant pollen from the male to the female reproductive structure. Pollination is how plants reproduce by moving pollen from one part to another to make seeds.

Rhizoid

A thin rootlike structure that absorbs nutrients and anchors nonvascular plants. Rhizoid. Rhizoids are hair-like structures that help certain plants absorb nutrients from the ground.

Rhizome

An underground stem of ferns that stores food. Rhizome. A rhizome is a horizontal plant stem that grows underground and helps store nutrients.

Seed

A plant embryo in a protective covering. Seed. A seed is a small, dormant plant embryo surrounded by a coat, storing nutrients needed for it to grow into a new plant.

Sepal

A leaf like structure below the petals, it protects the flower when it is a bud. Sepal. Sepals are parts of a flower that enclose and protect the developing bud before it blooms.

Spore

A reproductive cell that can grow into a new plant. Spore. A spore is a tiny cell produced by fungi, some plants, and bacteria that can develop into a new organism without the need for fertilization.

Stamen

The male reproductive part of a flower. Stamen. The stamen is the part of a flower that produces pollen, which is necessary for fertilizing the plant's ovules.

Transpiration

The loss of water vapor through the stomata in a plants leaves. Transpiration. Transpiration is the process by which plants release water vapor into the air through tiny openings in their leaves.

Tropism

A change in a plants growth in response to external factors, like growing towards the light. Tropism. Tropism is a plant's movement or growth direction in response to environmental stimuli like light, gravity, or water.

Vascular plant

A plant with specialized tissue to move water and nutrients. Vascular plant. Vascular plants have tube-like structures that carry water and nutrients throughout the plant.

Xylem

Plant tissue that moves water and nutrients up from the roots. Xylem is a type of plant tissue that acts like a straw, carrying water and nutrients from the roots throughout the plant.
