- Zone of elongation
- root hair function
- a A pollen-producing male reproductive part of a flower, consisting of a filament and an anther.
- b A sac in which pollen grains develop, located at the tip of a flower's stamen
- c root cells elongate, sometimes to more than ten times their original length; it is cell elongation that pushes the root tip farther into the soil; the cells lengthen, rather than expand equally in all directions, because of the circular arrangement of cellulose fibers in parallel bands in their cell walls. The cells elongate by taking up water and the cellulose fibers separate
- d - a plant that grows on another plant, usually anchored to branches or trunks of living trees. Ex. Orchids. They absorb water and minerals from rain
- e An outgrowth of an epidermal cell on a root, which increases the root's absorptive surface area.
5 Multiple choice questions
- - threadlike filaments that make up the body of a fungus
- proper irrigation (drip irrigation), prevention of erosion (planting rows of trees as windbreaks, terracing hillside crops, cultivating in a contour pattern), prudent fertilization (inorganic fertilizers, manure, compost,)
- An internal timekeeper that controls an organism's biological rhythms; marks time with or without environmental cues, but often requires signals from the environment to remain tuned to an appropriate period.
- The female part of a flower, consisting of a stalk with an ovary at the base and a stigma, which traps pollen, at the tip.
- nonvascular; mosses; apical meristems; embryophytes; lack true roots/ stems; no lignified cell walls lack support; grow close to the ground; need water for fertilization
5 True/False questions
Structure producing pollen grains → anthers
Fertile topsoil composition → An outgrowth of an epidermal cell on a root, which increases the root's absorptive surface area.
Monocot/Dicot seed differences- → Promotes fruit ripening
Long-day (short-night) plants → - Flowering occurs when the night length is less (10hrs)
- A dark interval that is too long will not produce flowers
- Flowering can be induced by a flash of light during the night
- Flower in the summer
- Ex. Potatoes, corn, marigolds, geraniums, begonias
Darwin's phototropism experiment → - Control
- Tip removed
- Tip covered by opaque cap
- Tip covered by transparent cap
- Base covered by opaque cap
1. Tip of shoot was responsible for sensing light
2. Growth response for the bending of the shoot occurs below the tip
3. Some signal was transmitted downward from the tip to the growth region of the shoot
