Anatomy Notecards 3 Flashcards
Nucleus
Control center for the cell
Nuclear membrane
Border for the nucleus with nucleoplasm inside where the nucleoli and chromatin are located
Chromatin
The threads that the duplicated DNA will be attached to when the cell divides
Plasma membrane
Outer boundary for the cell-regulates the the cell temperature, ph levels, and food entry
Cytoplasm
All the cellular fluid outside the nucleus and inside the plasma membrane. Keeps cell from drying out.
Small organelles
Performs different tasks for the cell
Inclusions
Sotres nutrients inside the cell that determine its specific job for the body
Centrioles
Begin the division process for the cell by forming spindle fibers
Golgi apparatus
Packages proteins and prepares them for for transport out of the cell
Lysosomes digest
Digest worn out organelles and helps digest food particles
Microvilli
Folds in the cell membrane that allow it to expand and shrink
Mitochondria
Controls the release of energy by breaking apart from ATP molecules
Ribosomes
Construction cited where proteins are put together
Rough endoplasmic reticulum
Prepares lipids to maintain the cell membrane, also contains ribosomes
Smooth ER
Sight of steroid synthesis
Cell physiology metabolism
Use of nutrients to build new cell parts by breaking down substances to make ATP
Solutions
Mixture of 2 or more components
Solutes
Substances present in the smaller amount
Passive transport
Substances are transported thru the plasma membrane without
Diffusion
Molecules going from an area of high concentration of ares of law concentration until it evens out
Larger
Molecules like sugar bond with a carrier protein and move the through the membrane passively
Osmosis
Diffusion through a selective semi-permeable membrane
Phases of mitosis
Interphase, prophase, metaphase, anaphase, and telophase
Protein synthesis
How proteins are made
Cytology
The study of cells
