Answer: When cells swell up
Explanation: Plants need carbon dioxide and <u>stomata allow the plant to take in carbon dioxide to perform photosynthesis</u>. The "lips" are actually individual cells (called guard cells) <u>that can swell up to open the stomata</u> or deflate to close them off.
By using the legend below the diagram, you can assume that Phase 1 indicates that meiosis has occurred because of the color of the arrow. The dark gray indicates haploid, and haploid is the result of meiosis. Diploid is the result of mitosis.
Another indication is the presence of sex cells or gametes in Phase 1. Meiosis produces gametes and in phase 1, you can see that egg cells and sperm cells were produced.
Answer:
C. Slide A, plant cells; Slide B, animal cells
Explanation:
The slide A has some organelles that are unique to plant cells, and are mostly found in plant cells. Organelles such as a cell wall and chloroplasts are unique features of plant cells. They are normally absent in animal cells.
Therefore, slide A, which has these cell organelles can be rightly labelled as "plant cells", while side B, which has these organelles missing, can be labelled as "animal cells".
