Question

I have a fill in the blank homework assignment on cells I really need help with! Thank you!

The (1) ________ is the fundamental unit unit of life whose control center is the (2) ________, a double membrane-bound organelle which contains the information storage molecule (3) ________. It can be copied to form (4) ________, which leaves via openings called (5) ________ ________ and attaches to small, membrane-bound organelles, (6) ________, the sites of protein synthesis. If they are attached to the outer surface of the ER or endoplasmic reticulum, this combination forms the (7) ________ ER that transports the proteins through a system of channels. If the ER lacks the protein synthesizing organelles on its membrane surface, it is (8) ________ ER.

Manufactured substances transported by the ER may eventually be housed in membrane-bound ER transport (9) ________ which form when part of the ER membrane pinches off. They are sent to the (10) ________ ________, chemically modified and repackaged into (11) ________ ________. One example of these repackaged organelles, (12) ________, contain digestive enzymes which can consume food, damaged organelles, or invading bacteria.

(13) ________ are double-membrane bound organelles in which cellular respiration occurs. As glucose is metabolized, the harvested energy is stored in energy storage molecules, (14) ________. Each of these organelles contains its own singular, circular chromosome. Autotrophic organisms such as plants trap light energy and (15)_______, organelles which possess the green pigment chlorophyll, are the sites of photosynthesis. These organelles also possess circular chromosomes.

Answer 1

The (1) Cell is the fundamental unit unit of life whose control center is the (2) _Nucleus_______, a double membrane-bound organelle which contains the information storage molecule (3) ___DNA (Deoxyribonucleic acid)_____. It can be copied to form (4) ______RNA (Ribonucleic acid)__, which leaves via openings called (5) __Nuclear Pores______ ________ and attaches to small, membrane-bound organelles, (6) ___Ribosomes_____, the sites of protein synthesis. If they are attached to the outer surface of the ER or endoplasmic reticulum, this combination forms the (7) ___Rough Endoplasmic Reticulum_____ ER that transports the proteins through a system of channels. If the ER lacks the protein synthesizing organelles on its membrane surface, it is (8) _Smooth Endoplasmic Reticulum ER.

Manufactured substances transported by the ER may eventually be housed in membrane-bound ER transport (9) __Vesicles_____ which form when part of the ER membrane pinches off. They are sent to the (10) __Golgi Apparatus______ ________, chemically modified and repackaged into (11) _Secretary Vesicles_. One example of these repackaged organelles, (12) Lysosomes, contain digestive enzymes which can consume food, damaged organelles, or invading bacteria.

(13) _______Mitochondrion_ are double-membrane bound organelles in which cellular respiration occurs. As glucose is metabolized, the harvested energy is stored in energy storage molecules, (14) ___ATP (Adenosine Triphosphate)_____. Each of these organelles contains its own singular, circular chromosome. Autotrophic organisms such as plants trap light energy and (15)___Chloroplasts____, organelles which possess the green pigment chlorophyll, are the sites of photosynthesis. These organelles also possess circular chromosomes.
