The Pteridopyhta, phylum of seedless vascular plants has about 1000 known living species, including those in the genera Lycopodium and Selaginella; the gametophyte of some of these species cannot photosynthesize, and instead uses mycorrhizae to obtain nutrients.
Explanation:
The pteridophytes, most advanced group of plant among the cryptogams i.e. seedless plants.
They are first land plants that have developed a well defined vascular system.
Ferns, horsetails etc are common members of this phylum.
Oxygen is made and so is glucose (its actually sugar, but glucose is better sounding) by combining carbon dioxide and water using light energy as a source of energy. Also like to make sugars.
Answer:
All living organisms need energy to grow and reproduce, maintain their structures, and respond to their environments. Metabolism is the set of life-sustaining chemical processes that enables organisms transform the chemical energy stored in molecules into energy that can be used for cellular processes Please mark it the brainliest
Explanation:
Answer:
<u> C) Each type of sensory receptor responds only to the stimulus that defines the receptor</u>
<u></u>
Explanation:
Neurons, specialized cells within the nervous system. These help with coordinated movement ad communication within the body through the transmission of electrical signals.
Sensory receptors are highly specialized neurons. These are able to detect various chemical and physical stimuli, and are classified by their ability to detect certain stimuli such as:
- photoreceptors
- mechanoreceptors
- chemoreceptors
- thermoreceptors
Sensory receptors respond to certain intensities of stimuli, instead of one specific stimulus. e.g. Mechanoreceptors within the skin can respond to pressure changes due to touch, but may also detect sound due to specific vibrations.
B. Carbon
Carbon is often called "The Element of Life" because it's found abundantly in all living and once living things
