  • (Parts of the cell) Which part contains water? A. cell wall B. chloroplasts C. cell membrane D. nucleus E. vacuoles.
    The vacuoles contain water. (E)
  • Why are plants green?
    Plants are green because the chlorophyll in chloroplasts is green.
  • What is the difference between a plant cell and an animal cell?
    The plant cell has a cell wall, chloroplasts, and a big vacuole.

    Nutrition and/or interaction and/or reproduction
  • Which vital function(s) is/are this: nutrition, reproduction, or interaction?
    Interaction

    monera, protists, fungi, animals, and plants
  • It this a plant cell or an animal cell?
    It's a plant cell.
  • What three vital functions do living things perform?
    Nutrition, reproduction, and interaction
  • Which of the 5 kingdoms are unicellular?
    Monera, protists, and some fungi.
  • What is the smallest unit that makes up a living thing?
    A cell.
  • What do we call living organisms that have more than one cell?
    Multicellular
  • What do plants use to reproduce?
    Plants use seed or spores to reproduce.
  • Which vital function(s) is/are this: nutrition, reproduction, or interaction?
    Nutrition
  • How do plants get nutrients?
    They use sunlight to make food.
  • How do animals reproduce?
    They give birth to babies or they lay eggs.
  • Where do monera live?
    They live on land, in the air, in water, and inside other living organisms. (Everywhere)

    Plants, animals, and some fungi.
  • (Parts of the cell) Which part controls substances entering and leave the cell? A. cell wall  B. chloroplasts    C. cell membrane  D. nucleus   E. vacuoles.
    The cell membrane controls substances entering and leaving the cell.  (C)
  • Why are plants rigid?

  • How many cells do unicellular organisms have?
    One cell
  • How do monera reproduce?
    They divide into two cells.
  • Which vital function(s) is/are this: nutrition, reproduction, or interaction?
    reproduction and/or interaction
