Scott Foresman Science Grade 5 Chapter 4
Growth hormone
A kind of chemical that affects plant growth.
Taproots
A large root that grows straight down. The largest root structure as the plant grows. May store food for the plant.
What happens after pollen moves to the pistil?
A pollen tube grows to the stamen.
Spore
A single plant cell that can develop into a new plant.
What is the structure of a plant's leaf?
A. Epidermis B. Spongy tissue C. Vessel tissue D. Leaf opening
Describe photosynthesis
A. It is the process that plant and some other organisms use to make sugar for food. B. carbon dioxide+water+sunlight energy= oxygen +sugar C. Chloroplast are the organelles responsible for photosynthesis D. Chloroplast are the organelle in plant cells that contains chlorophyll, which enables the plant to make its own food. E. Chloroplasts are cells and the outer layer of a leaf. The epidermis is tissue, the leaf is an organ.
What is Phloem?
A. Phloem are tissues that carry sugar away from the leaves. B. In trees the Phloem is just under the stalk, in fact, the bark is made of the dead phloem.
How are plants different than animals?
A. Plants make their own food, and animals don't. B. Plant cells are square, and animal cells are round. C. Plants are mainly green, while animals are all kinds of colors.
What are the three main parts of a seed?
A. Seed coat B. Embryo C. Endosperm
How do roots and stems help plants?
A. Stems and roots are major plant organs. Many stems hold leaves high which helps plants receive light and make food. Stems hold fruit and flowers on plants. Roots anchor the plant in the ground and hold it in place as it grows.
What are important facts about plant stems?
A. Stems are plant organs B. Stems hold plants up to get light.
Why is it important that tubes connect the leaf to the rest of the plant?
A. The tubes carry food to the rest of the plant. B. The tubes carry air (oxygen) to the rest of the plant.
Name four different ways that pollination can happen.
A. Wind B. Water C. Insects D. Animals
What type of root grows smaller and smaller and holds a plant in place, and helps it absorb water?
Fibrous roots, like grass and wheat.
Pollen
Grainy, often yellow powder that is made at the top of each stamen.
Monocot
Has one area of stored food. Veins are parallel fibrous root systems
Dicot
Has two areas that are easily split apart Veins branch out taproot systems
Fibrous Root
In this system many roots grow in out in all directions and divide into smaller and smaller roots.
What is a composite flower?
It is made up of many tiny flowers, like a sun flower.
How do leaves help a plant?
Leaves are made of cells & tissues, and the process of photosynthesis takes place in the cells.
Pollination
Moving pollen from the stamen to the pistil.
Embryo
New plant
Do all plants reproduce with flowers?
No, some plants have spores.
What types of stems have much less Xylem?
Non-Woody Stems
What are two examples of non-Woody Stem Plants?
Pea Pods Plants and Dandelions
What is the process of moving pollen from the stamen to the pistil called?
Pollination
Name the parts of the plant?
See diagram in the book
What type of root is large, grows straight down and stores food?
Tap roots, like a carrot.
What part of the flower produces pollen?
The Stamen
What part of the seed contains a new plant?
The embryo
What part of the seed contains a stash of food?
The endosperm
What part of the plant is an organ made of tissues of similar cells?
The flower
What part of the plant is responsible for the plants' reproduction?
The flower
What part of the flower is colorful and draws insects to the plant?
The petals
What is the female part of the flower?
The pistil, which a plant may have many of.
What part of the plant absorbs water?
The root
What part of the plant grows quickly and pushes through the soil?
The root
What part of the seed protects the embryo from insects?
The seed coat
What job do the roots have in a plant?
They absorb water and minerals, and hold the plant in place. They anchor the plant, and store food.
What are two examples of Woody Stem Plants?
Trees and Shrubs
Xylem tissues
Tubes that carry materials from the roots to the leaves.
Phloem tissues
Tubes that carry sugar away from the leaves.
Tropisms
Ways that plants change their direction of growth in response to the environment.
What types of stems have a lot of Xylem tissue?
Woody Stems
What two things do vascular plants have?
Xylem & Phloem
What does Xylem do?
Xylem carry materials from the plants roots to its leaves.
What is a Monocotyledon?
a flowering plant with an embryo that bears a single cotyledon (seed leaf). Monocotyledons constitute the smaller of the two great divisions of flowering plants, and typically have elongated stalkless leaves with parallel veins (e.g., grasses, lilies, palms).
What is a Dicotyledon?
a flowering plant with an embryo that bears two cotyledons (seed leaves). Dicotyledons constitute the larger of the two great divisions of flowering plants, and typically have broad, stalked leaves with netlike veins (e.g., daisies, hawthorns, oaks)., A flowering plant with seeds having two seed leaves
What is a Cotyledon?
a seed leaf of an embryo
Photosynthesis
the process that plants and some other organisms use to make sugar for food.
