Cells and Systems Unit Test Flashcards
Characteristics of livings things
Are made of cells Need energy Grow and develop respond to the environment, reproduce, have adaptions for their environment
Structure vs function
all organisms need to certian things to survive like move but different organism move differently some animals have wings some have feet some have tails just like moving theres different ways to breath like gills, lungs, spiracle,skin.
Variation in structures
structures used for function can be very differnt . similar organism have variataions in there body like birds have different beaks depending where they life
SLIDE 6
DO IT
Digestive system organs
Salivary glands Mouth, Esophagus stomach, liver, pancreas, Gall Blatter, small intestine, large intestine
Animals cells vs plant
Plant cell
Cell wall Chloroplast Nucleus to the side Vacole large Rectangular
Animal cell
Lysosomes
Nucleus yo the centre
Vacuole small
Rounded
Both
Golgi apparatuses Mitochondria Nucleus Nucleolus Endoplqwmic reticlum ER Vacuole Plasma membrane Cell membrane Ribosomes Cytoplasm
Cell wall
Outer covering of a cell that provides strength and support found only in plant cells
Chloroplast
Organelles that convert sunlight into food found only in some plant cells
Cell membrane
Your structure that encloses all the contents of the plant and animal cells as tiny openings that allowed particles of a substance diseases to pass through but not all
Cytoplasm
Contents of the cell inside the cell membrane excluding the nucleus contains nutrients the cell needs to survive
Mitochondria
Organelles that convert energy the cell revives into a form you can use
Nucleus
Organelle that directs all the activities in the cell
Vacuole
Organelles that store water and other substances we required by the cell
Golgi apparatus
A major organelle it’s acts to process and package the macromolecules such as proteins and liquids that are synthesized by the cell
Lysosomes
An organelle in the silo plasm containing degradative enzymes enclosed Ina membrane
Nuceolos
A small dense spherical structure in the nucleus of cell during interphase
Endiplasmic reticlum
A small sense spherical structure in the nucleus of a cell during interphase
Plasma membrane
The plasma membrane is the boundary between the celll and its environment. It regulate what enters and exits the cell
Ribosomes
A minute particle consisting RNA and associated proteins, found in large numbers in he cytoplasm of living cells. They bind messages RNA and transfer RNA to synthesize polypeptides and proteins
Multicellular
Made up of two or more cells
Unicellular
Made of one cell
Diffusion
Diffusion is the movement of particles from an area where there are more of them to an area where there are fewer of them
Or
They fusion moves particles from a more concentrated area to a less concentrated area to even them out
Osmosis
Osmosis is die fusion with water
Plant tissues
A plant has three main tissues 1. Phtosynthetic/storage 2. Protective 3.transport Xylem water and phloem food
