Answer:
While plant cells have chloroplasts to photosynthesize, they also require ATP for cellular functions, and do use oxygen to break down some of the sugar they produce in order to generate that ATP. They need mitochondria for this.
In particular, at night when there is no light, plants undergo cellular respiration since there is no sunlight to photosynthesize.
They do, however, produce far more sugar and oxygen through photosynthesis than they use up in respiration.
True, organisms take in nitrogen and carry out life processes.
Answer:
axon; dendrite
Explanation:
A neuron has three main parts. These are axons, dendrites, and a cell body. Synapse is the site of communication between two neurons. The first neuron of a synapse is called the presynaptic neuron (sending neuron) while the second one is called the postsynaptic neuron (receiving). The axon of the presynaptic neuron and the dendrites of the postsynaptic neuron communicate with each other at the synapse as the axon of the first neuron delivers the nerve impulse away from the cell body.
Dendrites function as the receiving or input portions of a neuron. The plasma membranes of dendrites have numerous receptor sites for binding chemical messengers from the presynaptic neuron.
