Question

name____ class__ date__ j. vacuoles. vacuoles are sac - like structures used by the cell to store various materials including water, wastes, and food. they are located in the cytoplasm. plant cell vacuoles are bigger than those found in animal cells. review questions 1. vacuoles are located in the __ and are used by the cell for __. k. lysosomes. membrane - bounded sacs, called lysosomes, contain digestive enzymes. they are involved in food digestion in one - celled animals. lysosomes destroy damaged or old cell parts or cells in multicellular animals. although they have been seen only in animal cells, plant cells are now thought to have a similar organelle. review questions 1. digestive enzymes are found in the ____ of the cell. l. chloroplasts. the organelles involved in the manufacture of food (photosynthesis) are called chloroplasts (figure 5 - 8). they are located in the cytoplasm and contain the green pigment chlorophyll. also present are enzymes (organic catalysts) that are necessary for food - making reactions. inside the chloroplasts are stacked disks called grana. it is in the grana that chlorophyll is held and light energy for photosynthesis is trapped. the spaces inside the chloroplasts contain a protein - containing fluid called stroma. the pigments in chloroplasts can be separated and identified by a laboratory technique called paper chromatography. this process involves putting a drop of plant extract along one edge of a square of absorbent paper. the paper is then dipped into a solvent. the solvent moves up the sheet because of capillary attraction. as the solvent moves the substances in the drop of plant extract are carried along at different rates that are unique to each substance. because of this movement the different substances separate at distinct places on the sheet of paper thus forming what is called a chromatogram. each substance can then be identified by comparing its position with the positions occupied by known substances under the same conditions. chloroplasts are also found in one - celled organisms called algae. because algae are not multicellular they are not classified as plants but as protists. green plant cells and algae make their own food by the process of photosynthesis. this process involves a series of complex chemical reactions that use light as an energy source. photosynthesis provides food for green plants and algae. the food that is manufactured by photosynthesis is also used by other living things.

Explanation:

For the first question about vacuoles, the text states that vacuoles are located in the cytoplasm and are used for storing various materials. For the second question about digestive - enzymes, the text mentions that membrane - bounded sacs called lysosomes contain digestive enzymes.

Answer:

1. cytoplasm; storing various materials
2. lysosomes
