Which organelles are found in a plant cell? Check all that apply. Endoplasmic reticulum centrioles cell wall vacuoles lysosomes
Shalnov [3]

Answer: Endoplasmic reticulum, cell wall, vacuoles, lysosomes, mitochondria, chloroplasts and cell membrane.    

Explanation: Following are the organelles found in plant cells.

Endoplasmic reticulum is the membrane bound organelle found in both plants and animals cells. The endoplasmic reticulum forms a network of canals it helps in transport of material in and out of the cell.

Cell wall is a rigid structural layer which forms an envelope around a cell. It is a rigid structural layer which is composed of cellulose. It provides protection to the cell and exhibit pores which facilitates the transfer of materials to pass to and from the cell membrane.

Cell membrane is a layer that surrounds the cell and separate it from the external environment. It is a selectively permeable structure which controls the material which is going in and out of the cell.

Vacuoles are membrane bound fluid filled organelles which store materials which are not required by the cells and helps in the waste disposal. They store materials like water, food, sugars, minerals and other waste products.

Chloroplasts are the organelles specifically found in the plant leaves. They have special pigment called as chlorophyll that traps the light energy from sun to conduct photosynthesis.

Mitochondria are tube like organelles these are the called as the powerhouse of the cell. Their function is in cellular respiration. They break the sugar molecules to produce ATP as a source of energy.

Lysosomes are the small sac like structures they exhibit a single membrane which contains strong enzymes which are capable of digesting cellular wastes. They also called as suicidal bags.

Centriole is an organelle which is not found in the plant cell. It is only found in the animal cells, their is a pair of centriole,  which are minute cylindrical organelles near the nucleus. These helps in the development of spindle fibers during cellular division.

Identify which type of reaction the feature occurs in.
Alex17521 [72]

Answer:

Light-dependent reactions:

- takes place in the grana

- release oxygen

- produces ATP

Light-independent reactions:

- fixes carbon dioxide

- take place in the stroma

- produce glucose

Explanation:

Photosynthesis is a biological process in which light energy is converted into chemical energy in the form of glucose. In chloroplast, photosynthesis occurs in two sequential stages.

  1. Light-dependent reactions
  2. Light-independent reactions (kelvin cycle)

The light energy is converted into chemical energy (NADPH and ATP) in the thylakoid membrane of chloroplast (light-dependent reactions). These energy molecules are utilized in the kelvin cycle (light-independent reaction) to assembled sugar molecules from CO2 in the stroma of the chloroplast.

What are some pros and cons of using a dispersant versus bacteria to deal with a very large spill and how would each one impact
gtnhenbr [62]

Answer:

it is toxic to the health

Explanation:

Dispersants create a toxic environment for fish by releasing harmful oil break-down products into the water. ... Dispersants and dispersed oil have also been shown to have toxic effects on bird eggs that are similar or worse than from untreated oil.
