what/where is the nucleus central structure of a cell enclosed in a membrane which is essential to cellular functions such as reproduction and protein synthesis
what is a semipermeable membrane a membrane which allows some molecules to pass through but not others
vaculoe a small cavity or space in cell protoplasm containing air or fluid
what is the difference between nucleoplasm and cytoplasm nucleoplasm- protoplasm making up the cell's nucleus cytoplasm- protoplasm not contained in the nucleus
name 2 types of protoplasm nucleoplasm and cytoplasm
where is the dna contained nucleus
what are the functions of the cell release of energy, consume oxygen, move substances in and out of cell, reproduce, metabolize nutrients, synthesize proteins
what is active transport requires energy from the cell or wraps itself around a foreign particle.
what is passive transport requires no energy; moves through solution methods of movement
what is phagocytosis the process of englufing a solid particle by forming a pocket with the cell membrane
what is pinocytosis process of engulfing a liquid particle by forming a pocket with the cell membrane
what is the difference between phagocytosis and pinocytosis phagocytosis- engulfing solid particles pinocytosis- engulfing liquid particles
what is osmosis solvent molecules pass through a semi-permeable membrane to equalize concentration on each side
what is diffusion particles move to equalize concentration throughout
what is the difference between osmosis and diffusion osmosis- move through semi permeable membrane to equalize diffusion- particles move to equalize
what is isotonic solution same concentration of dissolved particles as the solution with
what is hypertonic solution solution contains greater concentration of dissolved particles than the solution
what is hypotonic solution solution contains lesser concentration of dissolved particles than the solution
what is prophase process of moving to opposite sides of cell
what is mitosis occurs in all human cells except repoductive cells. have 2 daughter cells and 4 stages...prophase, metaphase, anaphase, and telophase
what is miosis occurs in reproductive cells. 4 daughter cells and 1/2 number is chromosomes
muscle tissue moves body by contraction/relaxation of pairs
nerve tissue conducts impulses throughout the body
epithelial tissue acts as a protective barrier from heat, cold, water loss, and bacterial invasion; aids in secretion and excretion

reticular location- spleen, lymph nodes, and bone marrow
adipose location- under skin as padding
what are the 3 types of connective tissue skeletal, visceral, cardiac
skeletal tissue striated, voluntary and found attached to bones
visceral tissue non-striated, involuntary, found in hollow organs
cardiac tissue striated, involuntary, found in heart
2 types of nerve tissue nueron and neuroglia
nueron found in nverve cells
neuroglia located in brain, spinal cord, and nerves
name main types of membranes serous, cutaneous, mucous, synovial
cutaneous membrane covers the body, found in epidermis and dermis
synovial membrane membrane lines the joint, tendones and bursae. aids in lubrication of joints
serous membrane membrane lines closed cavities of body...thoracic cavity, abdominal cavity, and sac that lines the heart
mucous membrane line nose, mouth, stomach, intestines...secrete mucous
