**Statement II and Statement III are correct.**

Solución

Let's analyze each statement regarding plants: **Statement I:** "Plants lack cell walls and are heterotrophic." - This statement is **incorrect**. Plants have cell walls made of cellulose and are autotrophic, meaning they produce their own food through photosynthesis. **Statement II:** "Plants have bodies made of three organ types, each made of three tissue types." - This statement is **correct**. Plants typically have three main organ types: roots, stems, and leaves. Each of these organs is composed of three primary tissue types: dermal, vascular, and ground tissue. **Statement III:** "Plants have a haplodiplontic life cycle with two multicellular stages." - This statement is **correct**. Plants exhibit a haplodiplontic life cycle, which includes both a multicellular diploid stage (sporophyte) and a multicellular haploid stage (gametophyte). Now, let's summarize the correctness of the statements: - Statement I: Incorrect - Statement II: Correct - Statement III: Correct Based on this analysis, the correct option is: **Statement II and III are correct.**

Let's break it down! Statement I is incorrect because plants do have cell walls made of cellulose and they are autotrophic, meaning they produce their own food through photosynthesis. Statement II is correct; plants indeed have three organ types (roots, stems, and leaves) each consisting of three main tissue types (dermal, vascular, and ground tissues). Statement III is also correct; plants have a haplodiplontic life cycle, which includes both a multicellular diploid phase (sporophyte) and a multicellular haploid phase (gametophyte). So, the correct choice would be "Statement II and III are correct."
