55. A biologist isolates numerous tiny, green pigment cells from a sample of lake water. The cells are covered with a mucilaginous sheath. They contain relatively large amounts of chlorophyll a and phycobilin pigments and lack a compact, organized nucleus.

Golgi bodies and a cell wall D. Thylakoids and a cell wall E. Chloroplasts and mitochondria

C6H12O6

Chloroplasts take Light + H2O + CO2 to produce what

mechanical support, provides site-specific protein synthesis, plays role in intracellular transport, makes secretory proteins and membrane components

Function of ROUGH ER (ribosomes present)?

Makes lipids (steroid hormones) and helps detoxify

Function of SMOOTH ER (No ribosomes)?

Help assemble amino acids into proteins Translate genetic instructions into specific polypeptides

Function of ribosomes?

cellulose

Humans cannot digest

Nonpolar

Most lipids are nonpolar or polar?

stores pigments, poisons, etc and its large vacuole allows for large surface to area ratio

Plant vacuole purpose

Amino (NH2) + Carboxyl (CO2H)

Proteins have two groups

Golgi complex

This produces lysosomes and provides synthesis and packaging of materials for transport in vesicles

Fatty acids + glycerol

What are lipids made from?

cisternae

What are the flat sacs called in the golgi complex?

Chlorophyll (a)

What do chloroplasts contain to light trap the pigment molecules and absorbs every wave length except the color u see?

Granum

What do the stacks of thylakoids form?

Nuclear envelope

What do the subunits of ribosomes move across to get to the cytoplasm?

ATP and NADPH2

What do thylakoids produce for Calvin Benson Cycle?

Makes sugar from CO2

What does the Calvin Cycle make?

Turn carbon into gas form into carbon solid form

What is carbon fixation?

Holds enzymes and increases surface area for ATP production

What is the purpose of cristae in the inner membrane of mitochondria?

Starch

What is used for plant energy?

In the nucleolus from RNA + proteins

Where are ribosomes made and from what?

Stroma

Where does Calvin Cycle occur?

Mitochondria (outer membrane is smooth while inner membrane is convulated with CRISTAE)

Which is a double membrane for compartmentalization?

C

Which of the following cells would most likely have the greatest concentration of densely packed rough endoplasmic reticulum? a. An amoeba engulfing small ciliates b. A bioluminescent bacteria cell c. A pancreatic cell engaged in the production of digestive enzymes d. A function phloem cell at maturity e. An epithelial cell whose DNA is replicating before mitosis

e

protein

Which of the following would be considered a polypeptide? starch glucose fructose protein

Lysosomes

Which organelle contains hydrolytic enzymes for intracellular digestion, recycles cells organic materials and causes apotosis/cell death?

smooth ER

Which organelle is NOT found in a prokaryotic cell a. DNA b. smooth ER c. plasma membrane d. ribosomes e. cell wall

lysosome

Which organelle is responsible for releasing hydrolytic enyzmes that can help to remove cellular debris?

vacuole

Which organelle releases cellular waste products?
