The vascular tissue in plants that conducts water and dissolve nutrients upwards from the root and also helps to form the woody element in the stem
What is the xylem?
100
Water turns into vapor and passes out through thousands of tiny pores (stomata) through the process of ____. It helps to cool the plant and pump water and minerals to the leaves for photosynthesis.
What is transpiration?
100
the transport of organic solutes in a plant
What is translocation?
100
undifferentiated cells that are undergoing active cell division; growth in plants are confined to regions known as _____
What are meristems?
100
When a seed germinates, a young plant is formed that grows roots, stems and leaves is in what phase?
What is the vegetative phase?
200
The vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves
What is the Phloem?
200
Fungus grows on the surface of the roots and sometimes even the cells of the roots to absorb mineral ions for the plant. In return, the plants supplies sugars and other nutrients to the fungus. This is called a ______ _____.
What is mutualistic relationship?
200
Produces sugar by photosynthesis in leaves or green stems or by hydrolysis of starch in storage vessels (germinating seeds or roots/tubers) and deliver these products via the phloem to the sink (roots, buds, stem, seeds, and fruits)
What is a source?
200
the most abundant auxin is ___. It has a role in the control of growth in the shoot apex, it promotes the elongation of cells in stems
What is indole-3-acetic acid (IAA)?
200
Name the male and female flower structure
What is (Female-carpel) anther, filament,petals and (male-stamen) stigma, style, ovary, and sepal?
300
The force that allows water to stick to the organic tissues of plants
What is adhesion?
300
Water enters the roots cells by the process of _____
What is osmosis?
300
The process whereby carbohydrates enter the sieve tubes at the source
What is phloem loading?
300
The direction of which stems grow can be influenced by
What is light and gravity?
300
these two factors affect the flowering and gene expression of a flower
What is light and temperature?
400
Growth towards or away from an external light sources
What is phototropism?
400
Water and ions can travel into the root by moving between cells or along cell walls is called what ___ ____
What is the apoplast pathway?
400
this cell maintains the sieve tubes and has many mitochondria to produce ATP for active transport of organic compounds into sieve tubes.
What is the companion cell?
400
An example of a plant that uses phototropism
What is a sunflower?
400
the transfer of pollen grains from the male anther to the female stigma;the pollen contains sperm; often facilitated by animals, wind or water movement.
What is pollination?
500
Plant hormones that promote positive phototropism in plants
What are auxins?
500
Water and ions can travel into the root by moving from cell to cell via the plasmodesmata through the ______ ______
What is the symplast pathway?
500
this organic compound is transported in the phloem because it is not readily available for plant tissues to metabolize directly in respiration and therefore makes a good transport of carbohydrate as it will not be metabolized during transport
What is sucrose?
500
An example of a plant that uses gravitropism
What are tree roots?
500
when a seed, formed from a fertilized ovule, is moved away from the parental plant to reduce competition for resources.
