SNC2D Biology terms

organs

Groups of tissues that work together to perform a specific function or related functions

stomach

large muscular sac that continues the mechanical and chemical digestion of food

Interphase

Cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases

Prophase

Chromosomes become visable, nuclear envelop dissolves, spindle forms

Metaphase

second phase of mitosis, during which the chromosomes line up across the center of the cell

animal tissues

epithelial, connective, muscle, nervous

plant tissues

Meristematic Tissue, Dermal Tissue, Vascular Tissue, Ground Tissue

Adult stem cells

undifferentiated cells found among differentiated cells in a tissue or organ

organ systems

A group of organs that work together in performing vital body functions.

level of organization

atom, molecule, macromolecule, organelle, cell, tissue, organ, organ system, organism

circulatory system

Transports oxygen, waste, nutrients, hormones, heat, etc... around the body

muscular-skeletal system

The muscles, bones, tendons, ligaments. Provides structures/support so that our bodies aren't a squished up blob. Muscles allow us to have movement.

nervous system

the body's speedy, electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems

digestive system

Breaks down food into absorbable units that enter the blood for distribution to body cells.

reproductive system

Reproduce offspring- produce male sex cells (sperm) and female sex cells (oocytes)

urinary system

Eliminates nitrogenous wastes from the body. Regulates water, electrolyte and acid-base balance of the blood.

cell division

Process by which a cell divides into two new daughter cells

apoptosis

programmed cell death

mitosis

part of eukaryotic cell division during which the cell nucleus divides

Anaphase

Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell

telophase

After the chromosome seperates, the cell seals off, Final Phase of Mitosis.

Cancer Cell

Cell that divides uncontrollably.

stem cells

unspecialized cells that are able to renew themselves for long periods of time by cell division

embryonic stem cells

embryonic cells, which can develop into any type of body cell

cell cycle

series of events in which a cell grows, prepares for division, and divides to form two daughter cells

cytoskeletonis

a network of protein filaments and tubules that provide structure, shape, and support to the cell, and plays a key role in intracellular transport and cell division.

vascular tissues

complex tissues responsible for the transport of water, nutrients, and food in plants, including xylem and phloem.

An onion root tip cell

cell under a microscope and notice a 'cell plate' forming in the centre

Differentiation

is the process by which unspecialized cells develop into specialized cells with distinct structures and functions, enabling the formation of different tissues and organs.

epithelial tissue

Groups of tissues that work together to perform a specific function or related functions, often forming a distinct structure in the body.

Mesophyll

Groups of tissues that work together to perform a specific function or related functions are essential for the overall operation of living organisms.
