Answer:

Plant cells have a cell wall, a large central vacuole, and chloroplasts, but a animal cell does not have those things.

Nucleus; contains DNA

Lysosome; breaks down nutrients and wastes

Vacuole; storage

Centrosome; has a role in Mitosis to seperate chromosomes

Chloroplast; photosynthesis

Endoplastic Reticulum; transport nutrients within the cell

Ribosome; protein synthesis

Mitochondria; breaks down glucose into ATP energy

Cell wall; a rigid membrane found in plants and some bacteria

Golgi apparatus; packages proteins made, exocytosis

Cell membrane; a flexible mebrane around eukaryotic cells

What does Louis Pasteur mean with “the role of the infinitely small in nature is infinitely large?

dolphi86 [110]

He meant the micro-organisms (microbes) are very small living organisms but plays an important role in maintaining life on earth. Microbes fix gases and break down animal matter and dead plants into simpler substances that are used at the beginning of the food chain. Pasteur shows that vaccines against infectious diseases can be manufactured.

QUESTION 2

ASHA 777 [7]

Answer:

Carbon dioxide

Explanation:

Xylem and phloem are the two conducting tissues of a vascular plants. They are referred to as vascular bundles. Xylem and phloem are responsible for conducting certain substances from one part of the plant to another.

The xylem is responsible for conducting WATER AND DISSOLVED MINERALS from the root of the plants to other parts e.g leaves, stem, flowers etc. while the phloem conducts sugar (product of photosynthesis) e.g glucose from the leaves of the plant to other parts including the stem, root etc.

According to this question, xylem or phloem does not conduct or carry gaseous substances like carbon dioxide (CO2).

Travka [436]

Answer:

Santi is walking barefoot through his yard when he steps on a sharp rock. The skin on the bottom of his foot sends this information through a(n) sensory neuron to his CNS. A(n) interneuron picks up this information and carries it to motor neurons of the CNS, which sends a signal to the muscles in his foot causing his foot to pull away from the rock.

Explanation:

The scenarios discussed in the question is known as a reflex action. In this action, specific receptors detect specific stimuli. For example, pain in the barefoot due to steeping on a sharp rock was the stimuli. This stimulus was detected by the sensory neurons. The sensory neurons turned this information into a chemical signal which was transported by the interneurons to the motor neurons of the CNS. The CNS detected the signal and gave information for a response as a result of which Santi pulled back his feet.
