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
What is the female gamete of the plant called?
Ovule
Which plants produce flowers during sexual reproduction?
Angiosperms
What is the difference between mosses and vascular plants?
Mosses have no vascular tissue, are very short, and do not have seeds.
Vascular plants have vascular tissue that transports fluid up and down the body of the plant.
What are two examples of vascular plants?
- Angiosperms
- Gymnosperms
What does the shoot system consists of and their functions?
Stems and leaves, in which photosynthesis takes place above the ground.
What is the function of the root system?
Anchors the plant and provides water and nutrients for the shoot system.
What is an eudicot?
a clade of flowering plants (angiosperms) which are mainly characterized by having two seed leaves (cotyledons) upon germination.
What is a monocot?
flowering plants with one seed leaf or a cotyledon emerging from their embryo.
What is the apical meristem?
Also known as the “growing tip”, it is a cluster of undifferentiated cells at the tip of a plant’s root or shoot that triggers the growth of new cells.
