Parts of the plant cell

DNA

(deoxyribonucleic acid). The chemical structure of genes which control inheritance.

RNA

(ribonucleic acid). A chemical important in taking blueprint messages from DNA of the nucleus to ribosomes in the cytoplasm for protein synthesis instructions.

mitochondria

The tiny rod-shaped cell bodies where aerobic respiration occurs; the cell powerhouses.

ribosome

The tiny, dot-like bodies in the cytoplasm or part of the endoplasmic reticulum; important in protein synthesis.

Although the following term is actually obsolete and somewhat misleading, the cell may still be referred to as a__________

simple cell

A chloroplast consists solely of a football shaped container of chlorophyll.

False

Ribosomes are made of RNA.

False

The construction of the cell walls of all plants is similar

False

Inherited physical traits are directly related to:

genes

The number of chromosomes within each species of plant or animal:

is reduced in half with reproduction

nucleolus

A smaller, darker body found in the nucleus; contains a concentration of RNA; associated with message transfer to the cytoplasm and cell division.

Green, football-shaped plastids that carry out the life-support system of photosynthesis.

Chloroplast

Major segments of DNA during cell division.

Chromosomes

The organic materials between the membrane and nucleus, which contains a variety of tiny bodies, or organelles.

Cytoplasm

Chemical messages originate from:

DNA

Flattened membrane sacs and tubes that are believed to be centers for collecting and packaging cell structures and enzymes.

Golgi bodies

Rod-shaped structures scattered throughout the cytoplasm that are involved with energy release.

Mitochondria

The cell headquarters and inheritance; controls and orders the activities of the cell.

Nucleus

Why is a cell analogous to an engineered watch?

because it consists of numerous interdependent subunits because coded information cannot arise from random processes

A feature of plants that gives shape and texture and provides support.

cell wall

A system of membranes that appears to be a factory for life processes and a cell communication system for chemical messages.

endoplasmic reticulum

A concentration of the nucleic acid RNA, which is important in carrying chemical messages to other bodies in the cytoplasm.

nucleolus

The basic food produced by a plant is:

produced by chloroplasts

ATP is a:

reactant yielding food molecules chemical associated with mitochondria a form of chemical energy

The transfer of information from the nucleus to organelles is accomplished by:

ribonucleic acid

The total energy production of a mitochondrion is enhanced by:

the large internal surface area

The two main functions of the Golgi body are _____. Select all that may apply.

to collect and package cell building materials and enzymes break down food molecules into energy secrete and store high-energy compounds produce energy by way of photosynthesis
