Week 7 Flashcards
What is meant by the term vascular plant?
A plant that has vascular tissue that allows it to conduct water and solutes throughout the plant.
Which plants are avascular?
Moss and algae. They lack vascular tissue.
Compare and contrast the function of xylem and phloem.
Xylem transports water and ions from the roots. Dead cells called trachaeids.
Phloem transports water sugars from the leaves to the rest of the plant. Living cells.
Which plants produce cones during sexual reproduction?
Gymnosperms: conifers like pine trees, first, and junipers.
What is the function of the root hairs?
Microscopic projections of the dermal cells of the root that create surface area that absorbs water and nutrients for the plant.
What are stomata?
Pores on the leaf surface where CO2 enters and O2 and H2O exit.
Where in the plant body does photosynthesis occur?
Ground tissue, primarily in the leaves.
What occurs at the apical meristem (shoot and stem)?
This region of rapid cell division is responsible for the extension of the roots and shoots, and gives rise to the primary plant body.
Where in the plant do we find stem cells?
In the shoot and root apical meristems.
What are the three types of tissue found in a plant?
- Dermal tissue: forms the outer covering of the plant.
- Ground tissue: carries out photosynthesis, stores photosynthetic products, and helps support the plant.
- Vascular tissue: conducts water and solutes throughout the plant.
Name the genus and species of the giant sequoia
Sequoiadendron giganteum.
The plant shoot contains two structures – name them.
- Stem
- Leaves
What is the function of the plant root?
It is the site of some important mutualistic relationships between the plant and bacteria and fungae. they anchor the plant
What is the function of the plant stem?
Support the plant and direct water and nutrients from the roots to other parts of the plant.
What is the male gamete of the plant called?
Pollen grain
