Hydroplasm is not a known metabolic sequence. Which of the following are NOT organelles found in animal cells? Nucleus and golgi apparatus b. Cellular membrane and cytoplasm c. Mitochondria and ribosomes d. Chloroplast and central vacuole Chloroplasts and central vacuole are important organelles in plant cells. Chloroplasts contain chlorophyll and are the site of photosynthesis. Central vacuoles are used to store water in plant cells. All the other organelles listed are important to the function of animal cells and plant cells. Light initiates different types of cellular reactions. Which of the following responses to light converts the energy from light into a gain of potential energy? Phototaxis c. Photosynthesis d. All of the above Photosynthesis is the process plant cells use to convert oxygen, water and sunlight into a usable form of energy. The product of photosynthesis is glucose sugar molecules.

Posted on 27-Mar-2021
When sexual reproduction occurs in multicellular organisms, a process takes place before cells fuse whereby a cell is left with half of its chromosomes, enabling the creation of a cell with a characteristic chromosome number. What is this process called? Osmosis c. Anabolism d. Differentiation During meiosis, gametes sex cells are formed by reducing the number of chromosomes found in somatic body cells by one half. This occurs so that when two gametes, one from each parent, fuse together, the embryo will contain the correct number of chromosomes. Without meiosis, offspring cells would contain double the number of chromosomes of normal adults and they would not be viable. Which of the following represents the largest group of biological classification?

Kingdom c. Class d. Genus Biology uses a system of classification to group organisms together based on their characteristics. The levels of classification, from largest most inclusive to smallest most specific , include domain, kingdom, phylum, class, order, family, genus, species. There are two types of cells, eukaryotic and prokaryotic. Which of the following cellular structures are found in both types of cell? Prokaryotic cells are found in bacteria and their structure is much more simple than eukaryotic cells. Prokaryotic cells have a few simple cellular structures such as a nucleoid region, ribosomes, and a plasma membrane. Eukaryotic cells have more highly developed cellular structures including organelles that support the function of the cell.

For example, mitochondria are organelles that synthesize energy; ribosomes synthesize protein; chloroplasts convert sunlight, carbon dioxide and water into oxygen and sugar. Internal complexity c. Size d. Ecological relationships Unicellular organisms are very small compared to most multicellular organisms. If they were as large as a multicellular organism, their surface area to volume ratio would be too low to support life. Staying small gives unicellular organisms a high surface area to volume ratio.

Larger cells have less surface area compared to their volume. Molecules move into the cell, out of the cell and through the cell slowly through the cell membrane. Having a large surface area provides more space for molecules to diffuse across the cell membrane and less of a distance to travel inside the cell to supply organelles with materials needed for metabolism. How many chromosomes does an individual human person have?
