Cell Processes
Everything you need to know to prepare for the cell processes test!
| Question/Term | Answer/Definition |
|---|---|
| What are the reactants of photosynthesis? | Carbon Dioxide, Water, Light Energy |
| What are the products of photosynthesis? | Glucose and Oxygen |
| What are the reactants of cell respiration? | Oxygen and Glucose |
| What are the products of cell respiration? | Water, Carbon Dioxide, ATP Energy |
| What organelle does photosynthesis occur in? | Chloroplast |
| What organelle does cell respiration occur in? | Mitochondria |
| What most likely came first in the evolution of the Earth, photosynthesis or respiration? | Photosynthesis must have been first to make oxygen for organisms that would eventually need it. |
| Which process, photosynthesis or cell respiration, is something all organisms do? | Cell Respiration |
| What is the main difference between aerobic and anaerobic respiration? | Aerobic requires oxygen |
| Which makes more energy, aerobic or anaerobic respiration? | Aerobic makes 36 ATP whereas anaerobic only makes 2 ATP |
| What does photosynthesis make that stores energy? | Glucose (sugar) |
| What does photosynthesis split? | Water |
| Why do cells go through mitosis? | To make new somatic or body cells for growth, replacement, cells get too big, asexual reproduction. |
| What kind of cells does meiosis make? | Gametes (sex cells) (sperm or egg) |
| How many cells are made at the end of mitosis? | 2 |
| How many cells are made at the end of meiosis? | 4 |
| Cell containing 2 sets of each chromosome | Diploid |
| Cell containing 1 set of each chromosome | Haploid |
| What are the 3 parts of interphase? | G1, S, and G2 |
| When are chromosomes/DNA copied? | Interphase (specifically S) |
| What is the order of the phases of Mitosis? | Prophase, Metaphase, Anaphase, Telophase |
| What happens in Prophase? | 1st see chromosomes/sister chromatids, nuclear envelope goes away |
| What happens in Metaphase? | Sister chromatids line up in the middle of the cell |
| What happens in Anaphase? | Chromosomes are pulled apart toward the sides of the cell by the spindle fibers |
| What happens in Telophase? | Chromosomes are on each side of the cell being surrounded by a new nuclear envelope. Cell starts to split into two. |
| What happens in Cytokinesis? | Cell is actually divided into 2 new cells. Each new cell goes into interphase. |
| What is different between animal and plant cells going through mitosis? | Animal cells have centrioles and asters with a cleavage furrow. Plant cells have a cell plate. |
| What holds two sister chromatids together? | Centromere |
| What pulls chromosomes apart during mitosis/meiosis? | Spindle Fibers |
| Why can't cells get too big? | Cell's volume increases faster than surface area. Large cells are inefficient. |
| How do photosynthesis and cell respiration relate? | The products of one are the reactants of the other. What one makes, the other one needs. |
| What is uncontrolled mitosis? | Cancer/tumor |
