Cellfies: Tiny but Mighty
Converts light energy from the sun into chemical energy.
Chloroplast
The internal balance of a system that keeps internal conditions stable.
homeostasis
The movement of molecules across a membrane without the help of energy.
Passive Transport
Requires energy for molecules to move across a cell membrane.
active transport
The division of the cytoplasm of a plant or animal cell into two
Cytokinesis
Not found in animal cells, this structure provides strength and rigidity to the plant cell.
cell wall
The movement of water through a semipermeable membrane from an area of low concentration of solutes to an area of high concentration.
osmosis
A factor that determines if a particle can passively move across a cell membrane.
particle shape
Energy is used to surround a molecule with a cell membrane and pinch it off into the cell.
endocytosis
It refers to the complete sequence of events involving interphase, cell division (mitosis/meiosis), cell growth, cell senescence/aging and cell death.
Cell cycle
The powerhouse of the cell transforms sugar into useable energy in the form of ATP.
mitochondrion/ mitochondria
The movement of solute particles from an area of high concentration to an area of lower concentration.
diffusion
Another factor that determines if a particle can passively cross a cell membrane.
particle polarity
It literally means “cell-eating”, (bringing “into the cell”) is the process of a cell ingesting material/ food
Phagocytosis
This is the stage of DNA replication
S phase or synthesis stage
Found in all cells and protects the cell and allows certain materials to move through it.
cell membrane
A type of solution that produces movement of water out of the cell, causing it to shrivel.
hypertonic
A factor that determines if a particle can passively pass across a cell membrane.
membrane composition
A process by which substances, after being acted upon by lysosomal enzymes, are packaged and then discharged out of the cell (lysosome cell)
Exocytosis
During Interphase, the chromatin network appears as isolated granules or as networks forming coiled filaments called _______.
chromonemata
Control center of the cell; it is only found in eukaryotic cells.
nucleus
A type of solution that has a lower solute concentration, causing water to move into the cell and make it swell.
hypotonic
A factor that determine if a particle can be passively transported across a cell membrane
particle size
The cell applies energy to this before the protein moves the substance across the membrane.
Transport protein
The first phase of meiosis wherein one cell which is diploid divides into two daughter cells, each of which is haploid. This is due to the separation of whole chromosomes (homologous chromosomes) and not chromatids which occurs in mitosis.
Reductional Division
