What is the difference between Trichome and filament?

What is the difference between Trichome and filament?

The key difference between trichome and filament is that trichome is a hair-like fine epidermal outgrowth seen on plants, while the filament is the stalk of a flower stamen that supports an anther.

What is the Trichome in algae?

Trichomes (/ˈtraɪkoʊmz/ or /ˈtrɪkoʊmz/), from the Greek τρίχωμα (trichōma) meaning “hair”, are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae.

What are trichomes in blue green algae?

The trichomes of many species contain at least two functionally different cell types: the bluish green photoautotrophic cells and the usually somewhat more voluminous colourless heterocysts. Depending on the species, they occur either terminally or they alternate regularly with the photoautotrophic cells.

What cell structure is found in cyanophyta?

Cell Structure of Cyanobacteria: Cell structure is typically prokaryotic— one envelope organisation with peptidogly can wall, naked DNA, 70S ribosomes and absence of membrane bound structures like endoplasmic reticulum, mitochondria, Golgi bodies, plastids, lysosomes, sap vacuoles.

What are the general characteristics of cyanobacteria?

They include glycogen granules, cyanophycin granules, carboxysomes (polyhedral bodies), polyphosphate (volutin) granules, and gas vacuoles. Heterocysts, akinetes, and hormogonia are some of the specialized cells and differentiation in Cyanobacteria.

What is the difference between bacteria and cyanobacteria?

Cyanobacteria is also known as blue-green algae. They differ from other bacteria in that cyanobacteria possess chlorophyll-a, while most bacteria do not contain chlorophyll. Chlorophyll-a gives them their characteristic blue-green color.

What are the characteristics of cyanophyta?

The Phylum Cyanophyta (Myxophyceae, blue-green algae) differs from other algae in having a procaryotic cell organization, i.e., it lacks organized double membraned nuclei, chromatophores and mitochondria, and possesses characteristic photosynthetic pigments including biliproteins, myxoxanthin and myxoxanthophyll in …

Are cyanobacteria protists or bacteria?

Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact!

What is the difference between Cyanophyceae and cyanobacteria?

Bacteria: Because most cyanobacteria are photosynthetic and often share the same habitat as eucaryotic photosynthetic protists (“algae”), they were previously classed as cyanophyceae, where “‑phyceae” in botanical nomenclature signifies eukaryotic “algae”.

How do cyanophyta reproduce?

Reproduction in Cyanophyta: The Cyanophyta are characterized by the complete absence of sexual reproduction; no sexual organs and no motile reproductive bodies have been observed. Propagation takes place by simple division, by spores (akinetes, endospores, and exospores) or else by fragmentation (fission).

What is Chromoplasm and Centroplasm?

a) CHROMOPLASM. It is the outer colored part along the cell wall, which contains blue-green pigments (Phycocyanin). It also prepares food material due to the presence of Chlorophyll pigments. b) CENTROPLASM OR CENTRAL BODY. It is the inner colorless part of the cell, which contains stored food granules.

What type of asexual reproduction is protozoa?

Asexual Reproduction in Protozoa: Protozoa usually reproduces asexually by binary fission and multiple fission.

What type of asexual reproduction is blue-green algae?

Cyanobacteria reproduce asexually, either by means of binary or multiple fission in unicellular and colonial forms or by fragmentation and spore formation in filamentous species. Under favourable conditions, cyanobacteria can reproduce at explosive rates, forming dense concentrations called blooms.

What are the 6 types of algae?

Different forms of algae:

  • Green algae (Chlorophyta)
  • Euglenophyta (Euglenoids)
  • Golden-brown algae and Diatoms (Chrysophyta)
  • Fire algae (Pyrrophyta)
  • Red algae (Rhodophyta)
  • Yellow-green algae (Xanthophyta)
  • Brown algae (Paeophyta)

Is algae a plant or animal?

Algae are photosynthetic creatures. They are neither plant, animal or fungi. Many algae are single celled, however some species are multicellular. Many, but not all of red and brown algae are multicellular.

How does algae reproduce select the best answer?

Select the best answer. Algae reproduce both sexually and asexually. Algae reproduce both sexually and asexually. This answer has been confirmed as correct and helpful.

What algae releases toxins that can kill marine life?

Fire algae

Is algae a microbe?

Algae are the organisms, often microorganisms, other than typical land plants, that can carry on photosynthesis. Algae are sometimes considered as protists with chloroplasts.

Which algae is responsible for main supply of oxygen in the atmosphere?

Green algae

How did oxygen get on earth?

Much of the CO2 dissolved into the oceans. Eventually, a simple form of bacteria developed that could live on energy from the Sun and carbon dioxide in the water, producing oxygen as a waste product. Thus, oxygen began to build up in the atmosphere, while the carbon dioxide levels continued to drop.

What is the most abundant gas in the atmosphere?


What are the 3 gases?

Nitrogen, oxygen and argon are the three most abundant elements in the atmosphere, but there are other key components that are required for supporting life as we know it on earth. One of those is carbon dioxide gas. Carbon dioxide makes up 0.04 percent of the Earth’s atmosphere.

What are the 5 gases?

Elemental Gases

  • Hydrogen (H)
  • Nitrogen (N)
  • Oxygen (O)
  • Fluorine (F)
  • Chlorine (Cl)
  • Helium (He)
  • Neon (Ne)
  • Argon (Ar)

What are the 3 most common gasses in Earth’s atmosphere?

Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere’s mixture of gases. The atmosphere also includes water vapor.
