Partial Pressure

Pressure exerted by a specific gas in a group of gasses

Trachae

Tubes in insects body for respiration

What is it called when the binding of one oxygen molecule makes it easier for others to bind

Cooperative Binding

Where does meiosis happen in males?

testes, its where sperm is produced

where are sperm stored/mature

epididymis

What do the vas deferent do?

transport sperm from epididimys to urethra

What do the seminal vesicles do?

produce fluids

What hormones are produced in the ovaries?

estradiol, progesterone

What is the oviduct?

the fallopian tube

Plasticity

Ability of same genotype to produce different phenotypes in response to the environment

What type of linkage are starch made of?

Alpha

What is the meristem?

part of the plant that does meiosis, found at roots and stem

What do apical meristems do?

primary growth (growth in length)

What type of meristem does secondary growth?

lateral meristems

What is alternation of generations

going from a diploid to haploid life cycle

What is a sporophyte?

diploid, produces spores

What is a gametophyte

haploid, produces gametes

What do guard cells do?

regulate GAS exchange

What is turgor pressure

The force of the cell membrane on the cell wall

caused by fluid

What are aquaporins?

Membrane proteins that act as water channels

What is a sink?

location where substance is used or stored

What is dormancy?

period with no growth

What is Xylem?

water conducting tissue

Explain cohesion tension theory

as water evaporates it passively pulls water up from the roots because the water molecules are all attracted to each other

What is Phloem

Sugar conducting tissue

What is bulk flow?

Movement from high to low pressure

Explain the pressure-flow hypothesis

Sugars move from high to low pressure, and the gradient is created by ATP-powered pump
