Growth
Apart from being found from the tip of the plant this hormone regulates growth patterns such as phototropism and ?
What are auxins
This term refers to the movement of pollen grains from the male anther of a flower to the female stigma, a crucial step in angiosperm reproduction.
What is pollination
Although rare, which type of plant has salt glands to secrete ions from leaves?
what are halophytes
These two properties aid in a plant's transpiration pull?
What is cohesion and adhesion
(growth)Cambium—> Winter months = less growth ; summer months = more growth)
What is the Main cause for the visible ring inside the tree trunk?
In this type of plant reproduction, offspring are produced by a single parent without the involvement of gametes, ensuring genetic uniformity with the parent.
What is Asexual reproduction
found in plants like the Venus flytrap, this adaptation allows them to capture and digest insects to supplement their nitrogen intake in nutrient-deficient environments.
What is carnivory or insectivorous adaptation?
Root hairs create a larger surface area to increase what?
What is Absorption of water and nutrients
This hormone, often referred to as the 'stress hormone' in plants, is involved in the closing of stomata, seed dormancy, and inhibiting growth.
What is abscisic acid?
this hormone, produced in parts of the seed embryo, is essential for breaking dormancy and initiating germination by stimulating cell division and growth
What is Gibberellin
part of a plant is unique to xerophyte?
What is the Epidermis/ root System
(light increases, temperature increases, wind decreases and humidity decreases
What abiotic factors affect transpiration? Name 4 and explain why for at least 1
dead cells linked end to end forming tubes called xylem vessels and tracheids
What is the xylem made of?
These two phytochromes play a major role in photoperiodism? What are their functions?
What is Pr and Pfr ?
this term describes the growth response of a plant part toward or away from an environmental stimulus, such as light or gravity, which plays a significant role in the orientation of seeds and seedlings.
What is tropism ?
an adaptation of xerophytes that allows stomata to stay closed for longer in order to store CO2 from night so that they require less CO2
Describe C4/CAM physiology
no nucleus and cylindrical
Give 2 structural properties of the phloem cells
Meristems are analogous to what animal cell?
What is stem cells
C= energy store)
( allows for water to enter
What are the roles of the cotyledon and the microphlye in a plant seed?
reducing salt concentration in the xylem by reducing apoplastic movement)
How do halophytes regulate ions in the cell membrane?
Produce and provide pollen
what is the function of the anther?
