Are the stem holdfast and blade of brown algae the same as stems roots and leaves of land plants?

Algae have neither. Species of multicellular algae grow a body called a "thallus." A thallus may be simply a long string of cells, a bush-like or a feather-like structure, or a superficially plant-like structure, like those seen in kelp.
The stem-like portions of a thallus (in those algae species that form a plant-like thallus) is sometimes called a "stipe." (The leaf-like portion is called a "blade," and the root-like portion called a "holdfast")

What plant has a thin stalk with tiny leaflike parts?
Typically a leaf is a thin, dorsiventrally flattened organ, borne above ground and, Furthermore, several kinds of leaf-like structures found in vascular plants are not totally. The internal organisation of most kinds of leaves has evolved to maximise of a petiole (leaf stalk), a lamina (leaf blade), and stipules.
Which part of brown algae is most important in photosynthesis?
Most macroalgae (multicellular algae) are made up of three parts. The blade is a leaf-like structure that captures light and carries on photosynthesis. The stipe is the stem of the algae. The holdfast is the anchor for the algae; it holds the algae to a solid surface such as a rock or pier. Although the holdfast may look like roots, it does not function to get nutrients or water. Some algae may have a fourth structure, the pneumatocyst; this structure is an air bladder on the stipe or blade that functions to keep the algae afloat in the water column.
How are leaves used as a means to identifying plants?
These things are considered: the shape of the leaves the margin of the leaves - serrated how the leaves are arranged on the stem - alternate, opposite etc if the leaves have hairs how the leaf blade is divided (or not) what the leaf stem is like what the veins of the leaf blade are arranged
What produces food for the cell through photosynthesis?
autotrophs
What is the leaf blade function?
The function of the leaf blade is to abosorb light and make food.
Why do you think that food is manufactured in the blade?
Maybe becos d food is transported frm d leaves 2 other parts of d plants.

Where does new growth in plants take place?
Fresh growth in plants is called the meristematic parts of the plant. On a blade of grass, it would be the tip of the blade.
What part of a plant is the blade?

What term describes leaves that are composd of two or more leaf lets on a common stalk?
The term that describes leaves composed of two or more leaflets on a common stalk is called compound leaves. Compound leaves have several leaflets attached to a central stalk, known as the petiole, rather than a single leaf blade. Examples of plants with compound leaves are poison ivy and clover.
