How many chromosomes are in their sex cells?
In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes. Human sex cells (egg and sperm cells) contain a single set of chromosomes and are known as haploid.
How many chromosomes are in plant cells?
Questions 122 – 125: If the diploid chromosome number of a flowering plant is 24, then the somatic cells of the plant each contain 24 chromosomes (12 maternal and 12 paternal).
How many chromosomes do pea plants have in the gametophyte generation?
Do pea plants self fertilize?
Pea plants also typically self-fertilize, meaning that the same plant makes both the sperm and the egg that come together in fertilization. This is done by transferring pollen from the anthers (male parts) of a pea plant of one variety to the carpel (female part) of a mature pea plant of a different variety.
Are Sporangia haploid or diploid?
The sporangium forms on the sporangiophore and contains haploid nuclei and cytoplasm. Spores are formed in the sporangiophore by encasing each haploid nucleus and cytoplasm in a tough outer membrane. During asexual reproduction, these spores are dispersed via wind and germinate into haploid hyphae.
Is a Sporangia diploid?
sporophyte – a diploid plant which produces spores. spore – haploid cell produced via meiosis in the sporangium of the sporophyte. It will develop into the gametophyte. sporangium – structure inside which diploid sporophyte cells undergo meiosis to become spores.
Do ferns make their own food?
Feeding: Ferns are producers. They make their own food by photosynthesis. They have chlorophyll just like most land plants. Environment: Ferns grow in cracks between rocks at the top of the shore or in old sand dunes.
Do ferns bear flowers?
Ferns are plants that do not have flowers. Ferns generally reproduce by producing spores. However, unlike flowering plants, ferns do not have flowers or seeds; instead, they usually reproduce sexually by tiny spores or sometimes can reproduce vegetatively, as exemplified by the walking fern.
Which chlorophyll is found in all algae?
There are four types of chlorophyll: chlorophyll a, found in all higher plants, algae and cyanobacteria; chlorophyll b, found in higher plants and green algae; chlorophyll c, found in diatoms, dinoflagellates and brown algae; and chlorophyll d, found only in red algae.
Does bacteria have chlorophyll?
Bacteriochlorophylls (BChl) are photosynthetic pigments that occur in various phototrophic bacteria. They were discovered by C. B. van Niel in 1932. They are related to chlorophylls, which are the primary pigments in plants, algae, and cyanobacteria….Bacteriochlorophyll.
