Biology: Cells

allow light to pass through the specimen

shines a beam of electrons through the specimen

use two lenses to form an image

samples must be preserved/ dehydrated, cannot see live organisms

allow light to pass through the specimen

shines a beam of electrons through/over the surface of the specimen

Activity of an organism depends on the activity of independent cells.

Cells contain hereditary information which is passed from cell to cell during cell division.

Energy flow occurs within the cell.

Cells are the basic unit of structure in living things.

All living things have cells

Cells in organisms of similar species have the same chemical composition.

Cells contain specialized structures to perform necessary functions for life.

Cells in organisms of the same species have similar cells.

Homeostatis is controlled by the cell.

Cells form tissues, which form organs, which from organ systems, which form organisms.

Cells can be specialized.

Cells are the basic unit of function in living things.

Cells come from other cells.
