Green protests are called plant-like protists‚ because they have chloroplasts. 4. Animal-like protest can breathe‚ and eat. 5. The euglena uses its whip-like "tail" to move. It flicks the tail and that propels it around. 6. The paramecium uses its cilia to move around randomly. 7. The amoeba uses its pseudo pod (false

head to tail condensation of polar monomers. Making Glucose: Green plants manufacture glucose through a process that requires light‚ known as photosynthesis. This process takes place in the leaf chloroplasts. Carbon dioxide and water molecules enter a sequence of chemical reactions within the chloroplasts. The end products of these reactions are glucose and oxygen gas‚ which is released into the air. Glucose is used by the plant‚ with much of it being converted into other carbohydrates like starch

Alisha Prakash Biol 111-513 The Properties of Water; Osmosis and Diffusion Hypothesis: When animal and plant cells are placed in a solution‚ the movement of water is effected by the solute concentration of the solution. If animal and plant cells are placed in a more concentrated solution‚ the solution becomes hypertonic to the cells‚ causing water to exit the cells. This changes the appearance of the cells‚ causing the cells to look darker (more concentrated) and shriveled up. Null Hypothesis:

their chloroplasts are often studied in order to understand the process of photosynthesis in more detail. Suppose you have a plant with no chlorophyll (it is an albino plant). Describe its appearance and the effect this would have on the plant. Albino plants are white because they lack chlorophyll in their leaves. Since plants use chlorophyll for photosynthesis‚ having no chlorophyll is a problem. An albino plant can’t make its own food so it must eat off other plants. a. Chloroplasts are the

dramatically increase the surface area of the inner membrane. Cristae extend into a dense material called the matrix‚ an area which contains RNA‚ DNA‚ proteins‚ ribosomes and range of solutes. This is similar to the contents of the chloroplast stroma and like the chloroplast‚ the mitochondrion is a semi-autonomous organelles containing the machinery for the production of some of its own proteins. The main function of the mitochondrion is the oxidation of the pyruvate derived from glycolysis and related
