Vocab 11
This is the study of plants.
What is botany?
This is the study of the life processes of an organism or, in other words, how something functions.
What is physiology?
Reproduction in this type of plant involves the formation of male and female gametes, pollination, and then finally fertilization.
What are angiosperms?
This type of plant tissue is where mitosis takes place. It also contains "stem" cells.
What is meristematic tissue?
This force which keeps the plant upright occurs when the central vacuole fills with water, pressing against the rigid cell walls.
What is turgor pressure?
Lifecycle in which there is a multicellular diploid (2n) and a multicellular haploid (n) phase and plants alternate between these 2 forms in order to reproduce.
What is the alternation of generations?
These are the basic of all cells that have not specialized in a particular function yet.
What are stem cells?
This is the mature ovary that contains seed/seeds, not capable of growing into a plant. But man is it delicious.
What is the fruit?
Plant roots function to absorb water and nutrients, anchor the plant, and this. if you eat a carrot, you are enjoying the benefits of this process.
What is store food?
This "movement" is a plant’s response to a stimulus such that the direction of the response is pre-programmed and NOT dependent on the direction of the stimulus. Remember the Mimosa plant?
What is nastic movement?
Fine dust that contains the sperm of seed producing plants. It's yellow and man it makes me sneeze.
NON-LIVING vascular tissue that carries water and minerals from roots to leaves.
What is xylem?
Gymnosperms reproduce by producing seed cones, which contain the female reproductive organs, and this type of cone which contains the male parts.
What are pollen cones?
Woody stems contain bark produced by cork cells. You should never girdle a woody stem because you'll disrupt this very important vascular bundle located in bark and the plant will die.
What is phloem?
This force, largely made up of the properties of cohesion and adhesion, helps water and nutrients travel up the xylem to the tallest portion of the plant.
What is capillary action?
Plants like petunias that live for only 1 year.
What are annuals?
The region of the root with undifferentiated cells that carries out mitosis. This is also located in the stem.
What is the apical meristem?
This sweet substance, which has glucose stored from photosynthesis, attracts bees and insects to it, which aids in pollination and therefore reproduction.
What is nectar?
This layer of cells shut off xylem and phloem when it senses shortening daylight. Then we enjoy watching the beauty of basically the slow death of leaves.
What is the abscission layer?
This process is basically the evaporation of water out the sides of the leaves. But it creates a powerful tension that pulls water up the stem.
What is transpiration?
The process that occurs when the embryo begins to grow under generally good conditions.
What is germination?
LIVING vascular tissue that carries sugar and organic substances through the plant
What is phloem?
This “seed” leaf that develops as part of the seed, provides nutrients to developing seedling and becomes the first leaf of the plant. You'll see mono- or di- as a prefix.
What is a cotyledon?
This type of vascular tissue is responsible for the appearance of tree rings, alternating light and dark rings that correspond to spring and summer growth.
What is xylem?
This process by which organic substances move through the phloem of plants requires energy! It's a good thing we didn't need to learn the details of it :).
What is translocation?
