What are the similarities between algae and plants?
Brown algal seaweeds have plantlike structures: the rootlike holdfast, which anchors the alga, and a stemlike stipe, which supports the leaf like blades Similarities between algae and plants are examples of analogous structures have two flagella, and each cell is reinforced by cellulose plates.

What type of alga is most likely a gelatinous seaweed?
A gelatinous seaweed that grows in shallow, cold water and undergoes heteromorphic alternation of generations is most probably what type of alga? Paulinella chromatophora is one of the few cercozoans that is autotrophic, carrying out aerobic photosynthesis with its two elongated "cyanelles."
Which four statements about Plasmodium are true?
Select the four statements about Plasmodium that are true. (1) Plasmodium cells infect two specific types of cells in humans. (2) Plasmodium cells infect two specific types of cells in humans.
Which of these algal groups possess a photosynthetic pigment?
Which of these algal groups possess a photosynthetic pigment that allows them to live in deep water? The phycobilins and other accessory pigments of red algae allow them to absorb the wavelengths of light that penetrate deep water and to use them in photosynthesis.
Which of the following are characteristics of red algae?
General Characteristics of Red AlgaeLack of flagella and centrioles.Presence of photosynthetic pigments.Found both in marine and freshwater.They show biphasic or triphasic life cycle patterns.They are a multicellular, filament, blade structure.Stored food is in the form of starch and polymers of galactan sulphate.More items...•
Which of the following are two groups that are adapted to anaerobic conditions and contain modified?
Which of the following are two groups that are adapted to anaerobic conditions and contain reduced mitochondria that lack DNA? Diplomonads and parabasalids are known for their reduced mitochondria.
Which of these characteristics is shared by algae and seed plants?
Which of these characteristics is shared by algae and seed plants? Both algae and seed plants have cells with chloroplasts.
Do green algae have chloroplasts?
The green algae (Division Chlorophyta) possess chlorophyll a and b within a double membrane-bound chloroplast. True starch is stored in the chloroplast and forms the principal photosynthetic product.
Do brown algae have chloroplasts?
Brown Algae. Phaeophyceae or brown algae are distinguished by chloroplasts that have four surrounding membranes, thylakoids in stacks of three, fucoxanthin that masks chlorophyll-a and -c, laminarin as the photosynthetic reserve, and alginates commonly as the wall matrix component.
Which of these groups includes both aquatic decomposers and the parasites responsible?
Which of these groups includes both aquatic decomposers and the parasites responsible for the powdery mildew of grapes and late potato blight? Water molds include both decomposers and the parasites responsible for the powdery mildew of grapes and late potato blight.
Are red algae acquired plastids by secondary endosymbiosis?
Although independent horizontal gene transfer events could explain this observation, the more reasonable explanation is that a secondary endosymbiosis event in red alga involved multiple gene transfers.
Which of these is the group of Chromalveolates that includes diatoms kelp and oomycetes?
Stramenopiles: Diatoms, Brown Algae, Golden Algae and Oomycetes. The other subgroup of chromalveolates, the stramenopiles, includes photosynthetic marine algae and heterotrophic protists. The chloroplast of these algae is derived from red alga.
Which of the following are shared traits of both plants and algal species that are most closely related to plants?
Explanation: Plants and algae are both photosynthetic. Both are also considered eukaryotes consisting of cells with specialized components. They both also have the same life cycle called alternation of generations.
Which of the following characteristics are shared by both green algae and plants?
Both green algae and land plants also store carbohydrates as starch. Their cells contain chloroplasts that display a dizzying variety of shapes, and their cell walls contain cellulose, as do land plants.
Which of the following characteristics are shared by both green algae and plants quizlet?
Which of these characteristics is shared by algae and seed plants? (Both algae and seed plants have cells with chloroplasts.)
Which algae contain both chlorophylls A and B?
3. chlorophytes Chlorophytes (green algae), like green plants, contain both chlorophylls a and b.
What pigments are used in photosynthesis?
1. red algae The phycobilins and other accessory pigments of red algae allow them to absorb the wavelengths of light that penetrate deep water and to use them in photosynthesis.
How do protists produce energy?
1. these protists produce chemical energy by fixing CO2 The term primary refers to the initial step of fixing carbon into a useable form for other organisms.
Which cell type has hairlike projections on its flagella?
3. Stramenopila Stramenopiles are characterized by cells that bear fine hairlike projections on their flagella.
Which bacteria share similar DNA to these photosynthetic bacteria?
2. endosymbiosis of cyanobacteria Chloroplasts share similar DNA to these photosynthetic bacteria , further supporting the idea of endosymbiosis.
Which cells lack mitochondria?
1. trichomonads … diplomonads The cells of trichomonads and diplomonads lack mitochondria.
What are the three seaweeds?
5. brown algae, red algae, and green algae All three of these are seaweeds
What do gametophytes produce?
Gametophytes produce cells that undergo mitosis to produce gametes that fuse to form a zygote.
What forms alternate with generations?
In life cycles with an alternation of generations, multicellular haploid forms alternate with
When do slime molds form?
Cellular slime molds form masses when food is scarce, but their cells remain separated.
What is the function of merozoites?
Merozoites live off the hemoglobin and nutrients in red blood cells and divide to produce more merozoites, destroying red blood cells in the process.
