How does a prokaryote differenciate from a Eukaryote? |
Prokaryote: Single-celled organism with no defined nucleous with membrane and no specialized organelles. Eukaryote: Can be multi-celled and and has a membrane bound where genetic material is stored. |
|
What is a heterotroph? |
A cell or organism that consums food produced by external sources. |
|
What is an autotroph? |
Autotrophs are self-feeders which produce their own foods. |
|
What is the equation for photosynthesis? |
6 CO2 + 6 H2O = C6 H12 O6 + 6 O2 Carbon dioxcide + water = glucose + oxygen |
|
What common trait do all living organisms share? |
Having a DNA-based microbe |
|
Name above ground plant parts. Name below ground plant parts. |
Above ground: Stems, stomata, cuticle, epidermis Below ground: Roots |
|
What are the functions of xylem and phloem? |
Xylem moves water and solutes upwards through plant. Phloem conducts food and water thoughout the plant. Both apart of the vascular system. |
|
What tissue type is responsible for plant growth? |
Meristem |
|
Name 3 leaf arragements |
Opposite, alternate, whorled |
|
Name the six elements that constitute organic material? |
Carbon, Oxygen, Nitrogen, Hydrogen, Phosphorus, Sulfur |
|
Name 4 types of organic molecules |
Carbohydrates Lipids Proteins Nucleic acids |
|
What are the building blocks of proteins? |
Amino acids |
|
What are the functions of RNA and DNA? |
RNA is involved in protein synthesis. DNA carries genetic material. |
|
Name a few common plant alkaloids. |
Nicotine, caffeine, cocaine. |
|
Name the levels of cellular organization |
Organism, organ systems, organs, tissue systems, tissues, cells, organelles. |
|
Name 3 plant organelles. Name 3 plant organs. |
Organelles: Mitochondria, nucleus, vacuoles. Organs: Stem, root, leaf. |
|
Where is DNA carried in a cell? |
Nuceus, mitochondria, and chloroplast. |
|
What is the function of Chloroplast? What is the function of mitochondira? |
Chloroplast: Photosynthesis happens here. Mitochondira: Cellular respiration happens here. |
|
What organ enables locomotion? |
Flagella |
|

1. Prophase 2. Metaphase 3. Anaphase 4. Telophase |
|
Name three meristems. |
Apical, primary, secondary |
|
What are the three tissue systems of higher plants? |
Ground, vascular, dermal |
|
Name the vascular tissues |
Xylem and Phloem |
|
What is a pigment and what is it's function? |
A substance that absorbs light. Pigments show relative effectiveness of wavelengths of light for photosynthesis. |
