What else can I help you with?
What is the number of chromosomes that the gametophytes of angiosperms have cells with nuclei have?
Gametophytes of angiosperms have cells with nuclei that typically contain a haploid number of chromosomes, which is half the number found in somatic cells. This means that gametophyte cells usually have one set of chromosomes.
Are The adult angiosperms diploid or haploid?
Adult angiosperms are typically diploid, meaning they have two sets of chromosomes in their cells. The haploid stage occurs during the formation of gametes (sex cells) through meiosis, where the chromosomes are reduced by half to create haploid cells.
What makes the female sex cells in a plant?
the ovules contained in the ovary are the female sex cells - in angiosperms
Do angiosperms have centrioles?
Higher plants and higher fungi both lack centrioles.
Do angiosperms have 'tracheids'?
yes. xylem tracheid occur in all plants included lower plant, gymnosperms and angiosperms. angiosperms had evolved to have another kind of xylem, that is xylem vessel, which is better in transport water, but tracheids still remain in angiosperms.
What are the male and female reproductive cells in a plant?
In plants, the male sex cells are called sperm (like in animals). These are produced from pollen, originating in the anther.
Are pineapples angiosperms?
Angiosperms.
What is the sugar-transporting cells in angiosperms?
In angiosperms, the sugar-transporting cells are known as sieve tube cells, which are part of the phloem tissue. These cells are responsible for transporting sugars, mainly sucrose, from photosynthetic tissues to non-photosynthetic parts of the plant for energy and growth. Sieve tube cells are connected end-to-end to form sieve tubes, allowing for efficient long-distance transport of sugars throughout the plant.
Do mature cells of phloem tissue in angiosperms have nuclei?
Mature phloem cells in angiosperms, specifically the sieve tube elements, lose their nuclei as they differentiate. This adaptation allows for more efficient transport of sugars and nutrients. However, companion cells, which are associated with sieve tube elements, retain their nuclei and play a crucial role in maintaining the function of the sieve tubes. Thus, while mature sieve tube elements lack nuclei, the companion cells do have them.
Which is not a way that angiosperms are useful to people?
A way that angiosperms are not useful to people as a major source of fertilizer. In angiosperms, after a zygot is formed a fruit forms.
Are sweet peas angiosperms?
Yes, they are flowering plants/ angiosperms
Are angiosperms autotrophic?
Angiosperms do not have chloroplasts. Chloroplasts play an important role in photosynthesis and angiosperms do not undergo photosynthesis thus, the absence of chloroplasts.
