Organs, Tissue, and Cells
The plant organ that does photosynthesis.
What are leaves?
Plants undergo this type of growth.
What is Indeterminate growth?
The type of life cycle of a plant that completes its life cycle in one year?
The annual cycle.
What is thicker?
Animal cells grow by metabolically expensive protein synthesis, while plant cells expand rapidly and cheaply because 90% of their expansion is caused by the intake of this substance.
Water
The root system that pierces deep into the soil.
What is the taproot system?
This type of growth is the growth in thickness.
What is secondary Growth?
This part of the plant is at the end of a root.
The root cap.
The tissue that makes up most of the tree trunk.
Secondary Xylem.
Aquatic Plant that demonstrates developmental plasticity by producing feathery, dissected leaves under water and oval lily pads on the surface
Cabomba aquatica
The leaf type that has branching, non-parallel veins.
What is an Eudicot?
The inner layer of the cortex is called this.
Root hairs increase absorption by doing what?
Increasing surface area.
Younger, outer layers of secondary xylem are called this.
Sapwood.
Because it has a short six-week life cycle, high seed output and a very small genome, this tiny weed became the first plant to have its entire genome sequenced
Arabidopsis
As an axillary bud grows, most of the growth is concentrated here.
What is the shoot tip?
The pores in the epidermis that help with gas exchange?
Stomata
One cell.
This tissue produces cork cells, replaces the epidermis as the plant gets thicker and helps protect the plant.
Cork Cambium
The plant cell fate is dominated by this type of mechanism, where an emerging cell communicates with its neighbours to figure out what to become.
Position based mechanism / positional information
Cells with very thick secondary walls.
What are Schlerenchyma cells?
Finger-like projections that leaves develop from.
Leaf Primidora
The Xylem in Eudicots are this shape.
Star-shaped.
This process gives hardness and strength to wood.
Lignin deposition.
According to the golden rule of mutual inhibition in the ABC hypothesis, if the A-class genes are mutated or suppressed, this class of genes will automatically take over the outermost whorls.
C-class genes
