Science Questions: Our Answers and a strong paragraph.

Science Questions and our answers:

a-   What is a thorn? What does it do? (p.99)

A thorn is a protective stem in a plant and thorns mainly protect the plant.

b-   What is the difference between vascular plants and other plants? (p.99)  Vascular plants have xylem and phloem to carry materials; however, other plants do not.

c-   What might happen if a tree’s bark were stripped away? (p.99). With no barks, the tree new phloem would be exposed and could be destroyed. The tree would not produce more phloem quickly and could die.

d-   What are taproots? How does it grow? (p.100). Taproots are roots that grows straight down into the soil.

e-   What is a fibrous root system? Explain. (p.101). Fibrous root system is a set of roots that grow out in all directions.

f-      How does a longer root system help a plant grow? (p.101) Longer roots help plants absorb more water, store more food or nutrients, and anchor the plant into the ground.

g-   What is the name for the small-modified leaves that cover the buds? (pp.102-103)

The small-modified leaves in plants are called sepals.

h-   What is the difference between pistol and stamen? (pp.102-103). A pistol is the female part of the flower and contain egg cells. Stamen is the male part of the flower and produces pollen.

i-      To what age must individual plants exist if their species is to survive? (pp.102-103).

All plants must live long enough so they can grow, reproduce, and die.

Your Strong Paragraph

Plants have many parts and each part has different functions working together as a system. A thorn is a protective stem in a plant and thorns mainly protect the plant. Vascular plants have xylem and phloem to carry materials; however, other plants do not. With no barks, the tree new phloem would be exposed and could be destroyed. The tree would not produce more phloem quickly and could die. Taproots are roots that grow straight down into the soil. Fibrous root system is a set of roots that grow out in all directions. Longer roots help plants absorb more water, store more food or nutrients, and anchor the plant into the ground. The small-modified leaves in plants are called sepals. A pistol is the female part of the flower and contain egg cells. Stamen is the male part of the flower and produces pollen. All plants must live long enough so they can grow, reproduce, and die.
