Answer in 3 sentences please.
Which characteristics of living things ensure the survival of the species?
What organelle allows plant cells to make their own food?
What is the function of the plasma membrane? What cells is it found in?
What organelle is responsible for processing sugar?
What is the function of a pseudopod? Where is it present?
What is photosynthesis? What cell does this process?
What is the difference between cells in leaves v. roots?
How do root cells obtain energy? What organelles are involved?
Why do animal cells not have a central vacuole or a cell wall?
How do unicellular organisms digest food differently than multicellular organisms?
1. Reproduction, adaptation, and genetic variation ensure the survival of the species.
2. Chloroplasts are the organelles that allow plant cells to make their own food through the process of photosynthesis.
3. The plasma membrane functions as a barrier, controlling the movement of substances in and out of the cell. It is found in all types of cells.
4. The organelle responsible for processing sugar is the mitochondria through cellular respiration.
5. Pseudopods are temporary projections of the cytoplasm used for movement and capturing prey. They are present in amoebas and other similar organisms.
6. Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen. This process occurs in the chloroplasts of plant cells.
7. Cells in leaves, specifically the mesophyll cells, are specialized for photosynthesis and have a higher concentration of chloroplasts compared to root cells, which are specialized for absorbing water and nutrients.
8. Root cells obtain energy through the process of cellular respiration, which occurs in the mitochondria.
9. Animal cells do not have a central vacuole or a cell wall because they have a different method of maintaining shape and stability, relying on their cytoskeleton and extracellular matrix.
10. Unicellular organisms can digest food intracellularly, within their own cell, whereas multicellular organisms have specialized organs, such as the stomach, that enable them to digest food extracellularly, outside of their cells.
1. The characteristics of living things that ensure the survival of the species include reproduction, adaptation, and the ability to obtain and utilize energy resources. These characteristics allow for the production of offspring, the ability to adapt to changing environments, and the acquisition of necessary nutrients for growth and survival.
2. The organelle that allows plant cells to make their own food is called the chloroplast. Chloroplasts contain a pigment called chlorophyll, which captures sunlight and converts it into energy through a process called photosynthesis.
3. The function of the plasma membrane is to control the movement of substances into and out of the cell, thereby maintaining the internal environment of the cell. It is found in all types of cells, both prokaryotic and eukaryotic, including animal cells, plant cells, and bacterial cells.
