Parts Of A Plant Cell
Which statements correctly refer to the organic protoplasm:
- the chemicals of the protoplasm are synthesized within the cell - the instructions for synthesizing protoplasm come from DNA
Why is a cell analogous to an engineered watch?
- because it consists of numerous interdependent subunits - because coded information cannot arise from random processes
ATP is a:
- product of decomposition of starch - chemical associated with mitochondria - a form of chemical energy
What cell part is described below? - The organic materials between the membrane and nucleus, which contains a variety of tiny bodies, or organelles.

What cell part is described below? - Flattened membrane sacs and tubes that are believed to be centers for collecting and packaging cell structures and enzymes.
Golgi bodies
A chemical important in taking blueprint messages from DNA
RNA
What cell part is described below? - A feature of plants that gives shape and texture and provides support.
cell wall
What cell part is described below? - Green, football-shaped plastids that carry out the life-support system of photosynthesis.
chloroplast
What cell part is described below? - Major segments of DNA during cell division.
chromosomes
What cell part is described below? - A system of membranes that appears to be a factory for life processes and a cell communication system for chemical messages.
endoplasmic reticulum
A smaller, darker body found in the nucleus
nucleolus
What cell part is described below? - A concentration of the nucleic acid RNA, which is important in carrying chemical messages to other bodies in the cytoplasm.
nucleolus
What cell part is described below? - The cell headquarters and inheritance; controls and orders the activities of the cell.
nucleus
