What are vascular plants?
Plants that have special tissues that form thin tubes inside the plant. These tubes carry water and other materials up and down the plant.
100
Why are two kinds of tubes needed in a plant?
Xylem takes minerals up from the ground and phloem takes nutrients down.
100
What do leaves do? And what two raw materials do they need?
A leaf is a factory that makes food (sugar). To make food, a leaf needs two raw materials: water and carbon dioxide.
100
Describe the xylem and phloem.
Xylem: moves water and minerals up from the ground through the root to the stem. Phloem: carries sugar from the leaves down the stem and into the root.
200
Describe the three main parts of a vascular plant.
Roots: anchor plants, take in water and minerals, store food Stems: support the plant, move materials from the roots to the leaves and from the leaves to the roots Leaves: makes food for the plant
200
Describe how vascular plants transport nutrients.
. The roots take in water and minerals from the soil. 2. Within the stem, tubes move water and minerals up from the roots to the leaves. 3. In the leaf, food is made in the leaves. 4. Stem: Tubes move the sugar to all parts of the plant.
200
What is a stomata?
They are tiny holes in the bottom of a leaf or stem. The stomata are surrounded by guard cells. When the guard cells open the stomata, carbon dioxide comes in. Guard cells can close the stomata to keep a plant from drying up.
200
Describe the gymnosperm.
A seed that does not produce flowers.
300
How are vascular plants classified? Describe the classifications.
Seedless Plants: grow from spores Seed plants: make and grow from seeds
300
What is the role of the cambium?
The cambium makes new cells of xylem and phloem.
300
What is the photosynthesis process?
It is the food-making process. Food is made in cells just under the epidermis. Food is made in chloroplasts. Carbon dioxide and water enter the chloroplasts. In the presence of sunlight, they form sugar and oxygen. After, phloem carries the food to all parts of the plant. Oxygen goes out the stomata.
300
Describe pollination.
It is the movement of pollen to the seed-making part of a flower.
400
How are seedless and seed plants different?
Seedless plants grow from spores. Whereas, Seed plants produce two special kinds of cells (male and female cells), they join together into one cell, inside the seed there is a new plant and those join together when the seed is made. Page 24 in IT book
400
Describe the light part of a tree stump.
The lighter part grows in the spring when water is usually plentiful.
400
What is the respiration process?
Respiration takes place in the mitochondria. Oxygen and sugar go into the mitochondria. The oxygen breaks down the sugar and energy is given off. Two waste products are made in the process: carbon dioxide and water.
400
Describe angiosperm.
A seed that produces flowers.
500
What do flowers do?
Flowering plants use their flowers for reproduction. 1. Pollination 2. Making a seed 3. Scattering a seed Look on page 27 in your IT book
500
Describe the dark part of a tree stump.
The dark part grows in the fall when there is less rain.
500
What two products do animal and plants give off?
Carbon dioxide and water.
500
What is a spore?
A single cell that can develop into a new plant exactly like the plant that produced it.
